Should I Replace a Damaged Wheel?

by

Every part on your vehicle is under pressure as you drive. Few parts, however, experience the daily bumps and grinds quite the way your wheels do.

Imagine the pressure placed on the wheels as you hit one of the infamous potholes that form over the long winter months here along the Front Range.

Or how about the way your wheels bounce and move when you take a dirt road?

Or even when your car touches the curb as you slide on ice buildup from the latest storm?

That bent wheel is telling you something. You may even feel it in the way your car drives.

Should you replace the damaged wheel? Should you repair it? Ignore it?

What are wheels made of?

The majority of wheels placed on vehicles today are made of cast aluminum alloy. They are created by pouring molten aluminum into a mold. This creates a lightweight yet strong product that, in general, works better than steel wheels used in the past. Because of how they are poured, they can take on many different looks and sizes, making them a popular choice for today’s vehicles.

Should I Replace a Damaged Wheel?The wheel is the structure surrounded and protected by the tire. The wheel has a center cap that sits in the middle, with a center bore in the back. They have lug holes where bolts are used to keep everything in place. You also have spokes, which connect the center of the wheel with the outer rim of the wheel. This is where the decorative part of your wheel exists. Finally, wheels also have an outer lip, a valve stem, and the barrel. Together, they create a wheel that holds up under all kinds of pressure.

Without a stable wheel, the tire can’t operate at peak performance. They work well when both are properly maintained. If any of the elements are damaged or not in optimal working condition, it’s important to get them repaired as quickly as possible, or replaced if they can’t be fixed.

What causes wheel damage 

Wouldn’t it be nice if you knew exactly what would cause damage to your wheels so you could avoid it? While there are a lot of variables in what can impact the wheels, there are a few guidelines that can help you become a more aware driver.

Driving on a flat tire – Have you ever watched a pilot walk around the plane before taking off doing a flight check? As a driver, you should have your own routine in place. As you walk up to your vehicle, glance at the tires – is one of them low on air, even flat? If your tire isn’t up for the job of protecting the wheel, it’s more likely the wheel will experience damage as you drive. Tires are designed to absorb the impact. They can’t do that if they aren’t in optimal condition. That means you should check tire pressure periodically and replace them before they further put your vehicle at risk.

Hitting a curb – how many times have you mistaken a driveway for a curb? You can tell when your car clunks and drops that the drop was larger than anticipated. Or maybe you turn a little too quickly and tap the curb as you’re turning a corner. We all do it. But that can also be a big problem for your wheels. The best course of action is to slow down and pay attention to where your car is moving.

Winter roads – sometimes bumps and dips in the road aren’t the only things to cause damage. Every winter, our roads are in constant flux with mag-chloride being sprayed on, sand and gravel laid into place, and ice and snow impacting our drive.  Driving through these chemicals and other pollutants can cause a buildup on the rims. Over time, depending on the metal alloy, these corrosive materials can eat away at the structure of the wheel until they break the seal with the tires. That’s a good reason to clean your vehicle frequently during the winter months to keep your car clean of these chemicals.

Be conscious of parking – if you frequently parallel park, how often do you touch the curb with your wheels? Do you bounce off the curb in front of you as you park in a lot? This constant scrape can wear down both your tires and your wheels until it causes serious damage.

Driving on rough pavement – sometimes there is no way to avoid rough pavement. And here in Colorado, the condition of the pavement changes all the time. Huge cracks sometimes seem to form overnight. Pop-up parking lots can have you traveling over gravel and stone. Have you ever followed Siri’s instructions and found yourself on rough, unknown roads? All of this can be hard on the rims, especially if your tires are weakened.

Hitting potholes – one of the biggest causes of wheel damage is potholes, something we get quite a lot of here, thanks to our winter conditions. You know the moment you hit one that your car has suffered from the impact. Even though you cringe when you hit one, it depends on the severity your wheels take the impact. Rough edges and the depth of the hole can all add into how much damage it sustains. If you suspect a problem, or notice a difference in the way your car drives, it’s time to schedule a check-up.

Replace or repair?

Wheels are built tough and should take quite a bit of impact as you drive. It all depends on the driving conditions, and how well your vehicle is maintained.

If you suspect an issue, don’t wait. Problems escalate quickly, and what started out as a simple repair suddenly turns into a major expense. A problem with your wheels could further jeopardize your tires, the brake system, or the suspension system. And as more repair work is needed, costs quickly follow.

Our team here at Express Car Care is ready to answer all of your questions, and get you back on the road as quickly as possible.

Spare Tire Care

by

Most of us don’t worry about getting a flat tire.  After all, it rarely happens, and if it does, we might think we can just call someone and have them put on the spare tire.  That’s a perfect plan if your spare is in good shape.  But how many of us even think twice about checking the condition of our spare tires?

The spares that take the biggest beating are those mounted outside the vehicle.  Like those on SUVs and trucks.  They might be on the tailgate or underneath the vehicle.  These get exposed to water, dirt, salt, and road debris.  The mounting hardware can become so corroded that you may not even be able to get the spare out of its holder, leaving you with no usable spare at all.

When you get your tires rotated, ask your service technician to check the condition and inflation of the outside-mounted spare and its holder.  A little lubrication and maintenance periodically can help keep them fit for action.  Often the spare on an SUV or truck is the same size as the other tires and may be included in the regular rotation – check your owner’s manual.

How about those compact spare tires that are sitting in the trunk, out of sight and out of mind?  They can have low air pressure too,  because over time, the air can slowly escape.  It’s a good idea to have your service facility check the spare’s pressure and condition at least twice a year, if not more frequently.  What good is a spare tire with inadequate air pressure?

And then there are the vehicles that don’t have spare tires at all.  They may have an inflator kit. These kits need to be kept in good shape, too.  Be aware that an inflator kit can’t fix many tire punctures and failures.  They frequently have a sealant in them that attempts to plug leaks and holes.  That sealant has an expiration date and should be replaced when it expires.  Again, ask your service adviser if your inflator kit is up to date and working.

Be fair to your spare and show it you care.

Why Are My Tires Always Flat?

by

Have you ever noticed that on your busiest days, that’s when your car seems to take on a mind of its own? You know what I mean if you’ve ever run outside, late for a meeting, and found something wrong with your car.

While a dead battery might stop you in your tracks, it isn’t the only thing that can cause you to be late. One look at a flat tire will tell you you’re not going anywhere until it’s fixed.

And while a flat tire can hold you back until you change it, what happens when you come out repeatedly to a flat tire? What do you do when your tires are always flat? Why does it keep occurring back to back?

There could be several reasons for that. Let’s go over each of them to help you narrow down what’s going on with your vehicle.

Age

While a tire that goes flat once could be from a variety of things, if it keeps happening, there’s something else happening with your tire. When was the last time you replaced your tires?

Tires have a very important job on your vehicle. They connect you to the road, keeping you comfortable and safe as you drive along. They are continually being subjected to all kinds of things: rain, sleet, snow, ice, dirt, debris, potholes, heat … You get the picture. Every day brings on a new set of experiences. And your tires are designed to take it all in, and continue to protect your car.Why Are My Tires Always Flat?

Tires are made from a variety of materials, including rubber. These materials aren’t designed to last forever; they will eventually wear out.

There isn’t one set of guidelines to help you determine exactly when that is. However, tires do come with suggested guidelines you should follow. A high performance tire may wear down faster than one designed for all-weather performance. It also depends on what driving conditions it faces each day.

While you can start by determining how many miles you’ve put on this set of tires, you should also take a look at wear marks. Tire makers state that tires should officially be retired when the tread depth reaches 2/32 of an inch. If you’re kind to your tires, they can last for years. If you drive aggressively, it can shorten the curve immensely.

Dry rot

Age can cause your tires to degrade over time. But age isn’t the only thing that can go wrong. While age, in general, will impact the tread of the tire, dry rot affects your tire’s sidewall.

Dry rot isn’t created from bacteria as it does in a forest. Instead, dry rot on your tire is caused by age or exposure to certain conditions. They include extreme temperatures, UV damage, extensive periods of long term parking, and corrosive chemicals.

Think all of that describes Colorado living perfectly this year? Yep, us too.

The way to prevent dry rot is through regular maintenance. Checking your tires regularly can ensure they are inflated to proper levels, and that you don’t notice problems with the tire tread before you hop on the road and drive.

If you do park for extended periods of time, (like we’ve been doing here in the middle of a pandemic,) be sure you check your vehicle periodically to ensure it’s in good condition. That includes starting the car and running it from time to time to keep the systems working, and checking to ensure the tires are properly inflated.

Valve stem

If you’ve recently changed a flat tire, only to have it flatten again a few miles down the road, it’s time to take a look at the valve stem. The valve stem allows you to regulate tire pressure. It includes both the stem core and the valve cap. You use the stem core to add air into your tires, while the cap is used to seal out dirt and debris from entering.

Just like the tire itself, the valve stem can wear down over time. And as damage occurs, it can cause leaks. Inspect the valve stem. Do you notice any cracks? Does it appear to work when you fill your tires with air?

If you’re having problems regulating tire pressure, bring your vehicle in and we can perform a thorough check. It’s often a good idea to replace valve stems at the time you invest in new tires. This ensures the materials used are fresh and new, ready to perform for thousands of miles as you drive.

TPMS

Built inside the valve stem is a tiny sensor that warns your vehicle’s monitoring system of potential problems. TPMS – tire pressure monitoring system – is designed to track the tire pressure inside each tire, and provide a warning signal when it falls short of being within the manufacturer’s guidelines.

Because newer cars are all computerized, you can monitor any changes to your vehicle by merely keeping a watchful eye on your dashboard. While the actual dashboard signal may vary slightly from car to car, when you see a new icon illuminated, it’s time to find out what’s wrong. If a light blinks on and off, it might be a change in conditions. If it continues, it is a sign something is changing in the way your car operates. The best way to get to the root of the problem is to stop by and have us run a diagnostic test. It will help pinpoint where the problem lies, fix it, and get you back on the road again in no time.

Are you tired of changing tires? Are you tired of finding your car not ready to drive as you head out to a busy day?

Whether it’s due to age, dry rot, or there’s a problem with your tire pressure monitoring system, we can help you pinpoint the problem, and get you back on the road in no time.

Tire Balance or Alignment – Which Does Your Car Need?

by

“My car shakes when I drive it.”

“My car veers off if I don’t hold tight to the steering wheel.”

Have you ever thought something similar when you drive your car? Maybe your car is in need of a tire balance or alignment.

Tire balancing and alignment are two phrases you might be familiar with. Drivers use them all the time. But what do they really mean? Are they the same thing? Can you use “tire balance” and “alignment” interchangeably for when you notice something wrong with the way your car drives?

What is tire balancing?

Tire balancing is also sometimes referred to as wheel balancing. Tire balancing corrects the distribution of weight onto each of the four wheels.

When a wheel is imbalanced, it leads to vibration while driving> If you’ve ever felt your vehicle shimmy and shake, it may be from imbalanced wheels. It can also cause excessive wear on the tires. If the tires don’t hit the pavement in the same manner on all four sides, it can cause some tires to wear faster than others. It can also damage the suspension system. The wheels are designed to keep your car stable as it moves. If it’s off balance, it can’t protect critical components of your car.

When a mechanic performs a tire balance on your vehicle, they apply zinc, lead, or composite weights to each wheel rim, both inside and outside. Because wheels are designed in different ways, there are several different types of weight application, determined by what your vehicle needs.

The weights are either pounded or taped into place to check balancing. Legislation has been enacted in some states to ban the use of lead weights, as many of them would fall off and wind up underground, potentially impacting our water supply.

What are the signs your car needs tire balancing?

Tire Balance or Alignment - Which Does Your Car Need?If you start to notice a vibration as you are driving, it’s a sign your tires need balancing. You might notice a shake in your steering column, feel it underneath your feet on the floorboard, or even notice movement in your seat.

Pay attention to the vibration as it can signal where your tires are out of balance. A tremble in your steering wheel can mean your front tires are impacted. If you notice your seat vibrating, it’s a sign it’s the back wheels.

You should also periodically inspect your tires. Do you notice uneven wear marks? Are certain parts of the tire wearing smooth before the rest? Does one tire look more heavily worn than others? All can be a signal your tires are imbalanced.

Also pay attention to your drive. Do you drive dirt roads frequently? Do you ignore potholes because you hit them often? Have you hit the curb recently? All of these things and more can damage your tires and wheels, and cause your tires to go out of balance.

What is wheel alignment?

Wheel alignment is also known as tire alignment. It refers to the practice of adjusting your car’s suspension system for a smoother ride. This isn’t an adjustment of the tires or wheels themselves, rather, the work is done to the suspension system to control the smoothness of the ride.

Alignment is what is needed to keep your car from veering off to the right or left when you drive. It can also improve the overall handling of your vehicle, and avoid certain vibrations that develop over time.

What are the signs your car needs a wheel alignment?

You might need a wheel alignment if you notice any of the following things:

  • Your car starts pulling to one side or the other while you drive
  • You notice uneven tire tread, or your tires are prematurely wearing down
  • You notice a squealing noise coming from your tires
  • You notice problems with your steering wheel, such as it tilts off-center, or vibrates when you accelerate

If you’ve been in a car accident, or you’ve recently slid into a curb, your vehicle is most likely in need of a wheel alignment.

Do I need a tire balance or wheel alignment?

Both tire balancing and wheel alignment should be a part of your regular maintenance routine. Just realize that the two are separate maintenance items, each being required to keep your car in good working condition as it ages.

While balancing is ensuring each individual tire is connecting well with the road, alignment is about modifying the angles of the wheels to ensure they are in proper position to each other, and to ensure the tires connect well with the road. An alignment ensures all four wheels are traveling in the same direction, and makes sure each tire stays well connected to the ground.

When do you balance your tires?

While it’s important to have your tires balanced if you feel a problem as you drive, there are also other times when you should rebalance your tires.

  • At a bare minimum, once every two years, more if you drive rough roads
  • When you get them rotated, which should occur about every 5,000 miles
  • When you have a flat and fix your tire
  • When you buy new tires
  • If you notice a weight missing from one of the rims
  • When you notice uneven wear on a tire

When do you align your wheels?

It’s suggested that you get your wheels aligned every time you have new tires put on your vehicle. You should also get an alignment:

  • If you have an accident
  • If you hit something, such as a curb, with your wheels
  • If you have severe wear on your tires
  • If you feel your car pulling as you accelerate
  • If you replace your tires

Keep in mind that not all vehicles need the same wheel alignment. A four-wheel drive doesn’t require a four-wheel alignment. Any vehicle with a single-tube axle can only have a front-end alignment.

And if your vehicle has other front end damage that may impact the alignment, it might be better off to wait until all work is completed. This way you won’t have to get an alignment twice.

What If You Leave Winter Tires On All Year?

by

This for a moment about a day of driving in January. You might start out with a sunny day on your way to work, but that can quickly change. Suddenly, the flurries start, it drops in temperature, and the snow starts to accumulate. Your drive home will be difficult at best.

Compare that to a day in the middle of July. You start out your day with a cool drive in, but the day quickly heats up from there. The temperatures climb – 80, 90, 100 degrees and more. It’s so hot even the pavement seems a bit gooey.

What about your tires? Should you prepare for each and get two separate sets? Or will one set of tires handle it all? Can you leave winter tires on all year? Or is there a better way to drive?

Get to know Colorado’s Traction Law

If you’ve ever driven Colorado roads, especially in the dead of winter, you know how treacherous they can be. When one car has trouble, spins out of control, and winds up by the side of the road, it can impact traffic for hours. It can turn one small accident into a major pileup in seconds.

What If You Leave Winter Tires On All Year?It can also be deadly.

The Traction Law is designed to require motorists to have:

  • 4WD or AWD vehicle with at least a 3/16 inch tread depth
  • Tires designated as mud and snow tires and a 3/16 inch tread depth
  • Winter tires with a 3/16 inch tread depth
  • All-weather tires with a 3/16 inch tread depth
  • Chains or an Autosock

It can go into effect at any time from September 1st to May 31st, depending on road conditions. If a Traction Alert is issued, you’ll have to stay off the road unless you have the specified tires on your vehicle.

This law was designed for two reasons. First, and the most obvious, is to keep Colorado drivers safe. Second, to keep the roads moving, and avoid hours of delay that can quickly occur in the event of a major pileup.

Your first question – Do your tires meet the Traction Law?

While this new Colorado law went into effect in 2019, if you haven’t evaluated if your car meets the guidelines, it’s time to give your tires a second look. All tires must have at least 3/16 inch tread depth to be considered compliant with Colorado law. If you aren’t sure what your tires’ tread depth is, measure it. Try this simple trick. Stick a quarter into the tread, making sure George Washinton’s head goes into the tire. If you can’t see the top of his head, your tire passes the 3/16 inch test.

However, don’t try the test just once and assume your tires are okay. Try all four tires. Try it in multiple places. In some cases, you might have a tire that isn’t wearing evenly, and you might be low in certain areas.

Don’t worry if you aren’t sure. The easiest (and possibly the best) way to determine if your tires are okay is to have them checked by one of our mechanics. We can tell you if they all meet required specifications, and how much traction you have left before replacement.

Winter tires, summer tires, what’s the difference?

Typically, you’ll find several different types of tires on the market: winter, summer, all-weather.

There are a few fundamental differences between them.

Winter:

Winter tires have a higher rubber content, which helps keep them softer, more supple when the temperatures dip low. The softer they are, the more able they are to grip the road surface in all kinds of weather conditions.

Winter tires have thousands of tiny grooves built into the tread blocks to disperse water and prevent hydroplaning. These grooves also can bite into the packed snow and provide optimal grip as you speed up and slow down.

Winter tires also have a deep tread pattern that allows snow to build up in the cavities. Snow helps grip snow, and intensifies the connection to the road.

Summer:

Summer tires are built from a harder compound that softens in milder and warmer weather conditions. This makes them more drivable on dry as well as rainy roads.

Summer tires have fewer grooves than winter tires, and are built more for handling afternoon rain showers and to prevent hydroplaning on suddenly wet roads.

Summer tires are made from a harder rubber compound that is designed to soften as the temperatures rise. They have more friction in the heat, which in turn gives you more fuel efficiency when the pavement reaches peak temperatures.

Summer tires also have a simpler block tread, which gives you better handling on hot roads, and has a massive impact on quickly you can brake.

All-season tires are somewhere in the middle. They are designed for average performance, no matter what the weather brings. You won’t have the grip and performance of summer tires, and will sacrifice more intense braking and handling in the winter. But overall, they get the job done.

Now let’s talk about winter tires. Are winter tires good all year long?

Should you leave your winter tires on all year? After all, the Denver metro area can see cold and snowy conditions ten months out of the year. It isn’t unheard of to have a snowstorm hit in May, while we’ve had sudden blizzard-like conditions as early as September.

And if you live in the foothills, the chance of snowfall increases from there. You might be tempted to trade in your tires for a good set of winter tires, and make those your year-round replacements. Here’s why you shouldn’t.

Winter tires are designed for traction and grip on snowy roads. They have unique features that make them great at what they do.

But if you leave them on, you’ll find:

They’ll wear down faster. Because winter tires are designed with deep treads that grip in cold weather, they can also wear down faster when they meet warm or hot roads day after day.

They won’t perform. You would never wear your snow boots to go jogging in the summer. You need the right tools for the job. Winter tires are designed for lower speeds and careful driving. When you want to hit the open road, you won’t get the same maneuvering or handling with winter tires.

You replace your tires faster. When we buy new tires, we focus on the manufacturer’s guidelines for how much mileage we can expect to see. If you’re not following the guidelines, the performance factors will decrease. You’ll replace your tires more often, and possibly have more problems (and repair bills) along the way.

It makes sense to have the right tire for the job.

Have you left your winter tires on all year long in the past?

Tire Rotation & Balancing

by

You can make the tires on your vehicle last longer with a regular tire rotation and balancing.

Let’s start with the tire rotation.  In normal driving around town, your front tires wear more on the shoulders because they handle most of the cornering forces in the turns.  If you’re driving a front-wheel drive vehicle, there is even more force put on the front tires.

The reason we rotate the tires is so that all of the tires have some duty on the front end and it also gives the back end a little break.  By doing a tire rotation, all four tires should wear more evenly over their life, this helps them last longer.

Most vehicles have their tires rotated front to back, but some manufacturers recommend a cross rotational pattern that includes the spare tire too.  If you drive a high performance vehicle, they might have different size tires on the front and rear, or they may have unidirectional tires that can only be on the left or right side of the vehicle.  If you drive this type of vehicle be sure to ask your service adviser to help you figure out just the right tire rotation for your vehicle.

Tire manufacturers always have recommendations for how often they want you to rotate your tires.  These recommendations usually fall somewhere around 5,000 to 8,000 miles or 8,000 to 13,000 kilometers.

Now let’s talk about wheel balancing.  Balancing is when there are heavy spots on the tire and wheel that causes it to wobble.

Wheel balancing is adding weights to the wheel that balance it out so it doesn’t wobble.  These are very small weight differences.  There are variations in tire and wheel manufacturing that can cause slight imbalances.  The valve stem and the tire pressure monitoring sensors in the tire can also make a difference.

Even small differences can cause annoying vibrations.  The wheel is basically bouncing as it travels down the road.  Say you were driving on the freeway, if your wheel is out of balance it can slam into the road 14 times a second.  Besides being annoying it also causes your tires to wear out quicker.

If you have a front wheel out of balance, you’ll feel a vibration in the steering wheel, and a rear tire will vibrate your seat.  If you have any type of vibrations in your vehicle, come in and see us.  We’ll see if it’s a balance issue or another problem.

Simple Answers About Selecting Tires

by

Question:  I need new tires, but how do I know which tires to select?

Express Car Care Answer:  Let’s look at selecting new tires in light of three factors:  Function, Fit, and Value.

Function:  This deals with what your needs are for new tires.  Weather conditions, terrain, temperatures, etc.

New family vehicles sold in Colorado come with all-season tires.  They can be used all year long and do pretty well on average road conditions – but they aren’t ideal in extreme conditions.

Winter tires have a more aggressive tread for handling snow and ice and they have a rubber compound that helps them have better traction as temperatures drop below 45 degrees Fahrenheit/ 7 degrees Centigrade.  In Colorado winter weather, that means better stopping and road-holding characteristics for driving than all-season tires.

Dedicated summer tires enhance warm weather performance driving.

If you drive off-road in the foothills and mountains around Denver, there is a spectrum of tire choices, from all-terrain ( a good mix of highway and off-road capability) to dedicated off-road tires.

The key to selecting tires is to discuss the function you’re looking for with your tire professional, so you get the type of tire, load rating, speed rating and wear rating you need.

Fit:  The easiest thing is to select tires in the same size that were installed at the factory.  If you want a different size wheel or tire profile, be sure to work with a professional that can make sure that your new wheels and tires fit properly and don’t rub when your vehicle bumps or turns.  It’s also important to make sure that safety systems like anti-lock brakes, stability control and traction control aren’t adversely affected by the new tire size. ( The computer may need to be recalibrated in order to make the necessary adjustments.)

Value:  Notice I didn’t say price.  The tire that meets all your needs and has the warranty and tread life you expect will probably not be the cheapest option – but it may well return the best value for your tire dollar.

Your friendly and helpful Express Car Care service adviser is ready and willing to discuss the options with you before you make this automotive decision.

Question on Tire Wear

by

Express Car Care Question:  My name is Dan. The tires on my vehicle wore out early and I had to replace them.  What can I do to make my tires last longer?

Express Car Care Answer:  Dan’s problem, premature tire wear, is a very common problem for Denver drivers.  Here are several suggestions on ways to lengthen your tire wear:

First, tires lose air pressure over time, so check the tire pressure at least once a month and fill them up as necessary.  A sticker on the driver’s side door jamb has the recommended tire pressure listed for your vehicle.

Another suggestion for lengthening tire wear is tire rotation.  Tire rotation is an important step in increasing the life of tires.  Your front tires take the brunt of stopping and steering forces, so they wear out faster than rear tires.  They should be rotated regularly so that all four tires are allowed to wear more evenly.  Talk to us at Express Car Care if you’d like more information on tire rotation.

Out of balance wheels can also cause a tire to wear out too fast. If you feel a vibration in your seat or steering wheel when you’re driving, you may have a wheel out of balance. It’s important to have your wheels balanced properly so the tires wear as evenly as possible.

Finally, a poor wheel alignment and worn or damaged suspension can chew through a tire very quickly.  Ask your friendly pros at Express Car Care to have your tires inspected for signs of premature tire wear.  Your technician will be able to pinpoint the cause and take care of it.

These are just some simple steps you can take to prevent premature tire wear.  Give us a call and let us know how we can help.

Tire Rotation & Balancing Answers

by

Question:  How do I know when I should get my tires rotated and balanced?

Express Car Care Answer:  The interval for tire rotation could depend on a recommendation from either the tire manufacturer or the vehicle manufacturer.  The background question for drivers is “why do tires need to be rotated?”

Front tires wear differently than the rear tires because steering wears the shoulders faster up front.  Rotating the position of the tires allows for more even wear among all the tires.   The suspension set-up on certain vehicles may also affect the relative wear between the front and rear tires.  There are several tire rotation patterns and your knowledgeable Express Car Care professional will make sure that you get the correct pattern for your particular vehicle.

Wheels and tires are not perfectly balanced due to slight variations in the manufacturing process and the placement of tire pressure monitoring sensors.  So weights are strategically placed on the wheel to ensure that the tire spins true.  When a wheel is out of balance it is essentially bouncing thousands of extra times as you drive.  This can result in an uncomfortable vibration for drivers in the steering wheel or through the seat.  An unbalanced tire will also wear more quickly and it’s also punishing on your shocks and struts.

Drivers should have their wheel balanced if they detect a vibration or uneven wear.  A wheel balance check every year is a good idea.  Because tires cost so much in our area, it’s a great idea to do everything you can do to make them last as long as possible.  Proper inflation, regular tire rotation and balancing are the keys to long tire life.  The team at Express Car Care can check your tires for signs of uneven wear and diagnose and correct the problem.

Simple Answers About Winter Tires

by

Question:  What is the benefit of winter tires?

Express Car Care Answer:  This is a really good question.  Most new vehicles in Denver come with all-season tires that work pretty well in winter conditions that many drivers may encounter.  First, let’s talk about the things that dedicated winter tires do really well, we’ll touch on all-season tires, and then you should have enough information to help you in your tire selection.

The first thing to take into account about winter is fairly obvious, it’s cold.  The rubber compound used in summer and all-season tires gets a bit hard when the temperatures drop below 45 degrees Fahrenheit or 7 degrees Centigrade.  Winter tires, on the other hand, stay more pliable when the thermometer takes a dip.  This means better dry road traction in the cold.

Ice and snow is the next thing drivers need to consider during the winter.  Some drivers live where there is a lot of snow, a lot of the time.  Extreme winter condition snow tires have a tread design that cuts into and expels deep snow for maximum traction.  These tires have a mountain and snowflake icon on the sidewall of the tire.

If you live in an area where the ice and snow are more moderate, you can still benefit from having winter tires.  Their tread has many small “cuts” called sipes that really help them get a grip on ice.

Now, all-season tires are a year-round compromise between high summer performance and high winter performance.  They just don’t perform as well in extreme conditions as the tires that are dedicated to either summer or winter driving.  For example, winter tires offer 25% to 50% more traction than all-season tires.  And studies have shown that all-season tires can take upwards of 40% longer to stop than winter tires.  This could be enough of a difference to prevent getting stuck or getting in an accident.

So what’s the best tire for you?  Talk to  your service adviser about the conditions you drive in throughout the year and how important performance is to you.  For many drivers that put a premium on handling performance, dedicated summer tires in summer and dedicated winter tires in winter are what they need to satisfy their performance needs.  Other drivers don’t have that same need and all-season tires work well for them.

Whatever you choose, winter tires or all-season, we are ready to mount them for you, come on in and see us.
