Tire Condition

by Leave a Comment

Did you know that the condition of your tire can tell you a lot about your car?  We can learn quite a bit about our vehicles by the way our tires wear. Tire condition is determined by the wear patterns.  Abnormal wear patterns can often alert us to the need for simple tire maintenance or the need for a front-end alignment.  Being aware of these patterns and how to interpret them can help you lengthen the life of your tires and improve the overall performance of your vehicle.  Below is a list of common tire wear patterns and what they might indicate.

Condition:  A tread cut or puncture is caused when a foreign object penetrates the tread area.  This can lead to air loss or possible tire destruction.

Solution:  If a puncture occurs, have the damage repaired if possible.  Your service technician can determine if the puncture can be repaired.

Condition:  Wear on one side of a tire can be a sign of misalignment or worn parts.  This condition will shorten the life of the tire and may lead to other tire damage.

Solution:  Have the vehicle inspected for possible mechanical or suspension problems that should be repaired.

Condition:  Shoulder wear on both sides of a tire.  This happens when the tire is under-inflated and the outer shoulders are forced to carry most of the weight.  This will lead to extreme shoulder wear and shorten the life of the tire.

Solution:  Keep the tires inflated to manufacturer’s recommended level.

Condition:  Center tread wear.  This type of damage can be caused by over-inflation.  The center of the tread will bulge outward, forcing the majority of the weight to be carried in the center of the tire which causes premature wear.

Solution:  Maintain the vehicle manufacturer’s recommended inflation level.  These are usually found inside the driver’s side door jamb.

Good driving habits and preventative maintenance, which includes proper air pressure, tire balance, alignment and rotation can add miles to the life of your tires as well as safety for you and your family.  If we can help you with any of these or other auto repair needs, call us at (303) 691-2760 or stop by our shop.

When Do You Replace Tires

Your ability to control your vehicle depends on the traction between your tires and the road.  Tires don’t need to have tread designs or much tread depth to give you traction on a dry road, but tires do require tread designs to generate traction on wet, slushy or snow-covered roads.

A tread design is necessary to direct water and slush from between the tire and the road, as well as provide edges that cut into the snow.  When water collects on the road surface during a rainstorm, the depth of the water, the speed you are driving and your car’s weight, along with the tires’ tread design and depth, are all factors in determining when and if the tires will stop the car quickly or force it to hydroplane or float.    

It isn’t difficult to understand that the tread on tires will wear away over their life and the volume of their tread grooves will be reduced.  This is a gradual process and you may not notice it day-to-day, but eventually there will be a time when you notice your car slip in the snow or hydroplane in the rain or just not stop quickly when the road is wet.

So when do you replace tires?  If rain and wet roads are your main concern, it’s recommended you replace your tires when they reach approximately 4/32″ of remaining tread depth.  Since water can’t be compressed, you need enough tread depth to allow the rain to escape through the tire’s grooves.  If the water can’t escape fast enough, your vehicle’s tires will be forced to hydroplane on top of the water, losing traction and increasing your stopping distance.

If you drive on snow-covered roads you should replace your tires when they reach approximately 6/32″ of remaining tread depth so you can maintain good mobility.  You need more tread depth in snow because your tires need to compress the snow in their grooves and release it as they roll.  If there isn’t sufficient tread depth, the “bites” of snow your tires can take on will be reduced and your vehicle’s traction and mobility will be sacrificed.

While replacing your tires before they are completely worn out may not seem to be very economical, it is far less expensive than repairing your car after you’ve had an accident because your tires needed to be replaced and weren’t!

When you replace the tires on your vehicle it is recommended that you replace all four tires at the same time and also have your car checked to make sure it is aligned properly.  All these steps will give you longer life for your replacement tires.

Best Tires For Colorado Winters

by Leave a Comment

It’s that time of year again!  The air is colder, the leaves are falling and we need to prepare ourselves and our cars for winter!  One of the ways to prepare our car is to find the best winter tires for them.  Summer tires are designed to enhance traction in mostly dry and warm conditions, not winter conditions.  Wintertime has the most challenging driving conditions that we face all year.  We have less daylight and colder temperatures as well as snow, slush and ice.  We need the best winter tires on our car to get us where we need to go safely.

Tire experts, including Tire Rack say only dedicated snow tires will actually improve your vehicle’s grip in winter conditions.  All-season tires are suppose to provide traction in a variety of weather conditions but fall short in their performance on ice and snow.  An inexpensive winter tire performs better in ice and snow tests than all-season tires.

Best Winter Tires

Narrow winter tires are better for driving on ice and in snow, they are better at cutting a path through snow and slush.  It’s always best to use the tire size specified for your car.  You can find that information in your owner’s manual or by looking on the sidewalls of the tires that are already on your car.

Do you need a studded winter tire? Is that the best choice  for your car?  If you drive on icy roads regularly, the studded winter tire might be your best choice, just be sure that they aren’t banned or limited in your area.  If you are curious about which brands are rated  the best winter tire, talk to your service technician or visit consumersearch.com/snow-tire/reviews. Once you have decided on the best winter tire for you, you’ll want to have them installed before the weather turns.  It’s also important that you get four matching tires.  It may be tempting to buy only two tires, but experts don’t recommend it.  Different tires react differently, and unmatched tires can handle unpredictably.  Another small tip is winter tires wear faster than regular tires, so remove them as soon as the winter weather is gone and spring arrives!

When To Replace Tires

by Leave a Comment

The condition of the tires on your car greatly affects your safety while driving.  Here are some tips to help you determine when to replace your tires.

  1. Look at the tread pattern. Most tires are manufactured with “tread wear indicator bars” built right into the tire itself.  They usually look like small bridges in between the tread.  When these indicator bars become flush with the tire’s tread that is a sign it’s time to replace the tires.       When To Replace Tires
  2. Check the tread depth. The “penny test” has been a popular method for a while, this is how it works.  Take a penny and place it upside down with the picture of the head facing you in the center of the thickest part of the tire tread.
  • If you can see the very top of the head, or the copper above it, replace the tires as soon as possible.
  • If the hair on the top of the head is somewhat visible, this mean you should begin looking for replacement tires.
  • If you can’t see the hair on the top of the head, then this means your tires don’t need to be replaced yet.

This is a simple method that works well if you are driving mainly on dry roads.  If you drive on wet, slushy and snow-covered road you should maintain a deeper tread depth on your  tires and replace them at the second bullet above.  You need enough tread depth (4/32″) to allow the water or slush to escape through the tire’s grooves.  If the water can’t escape fast enough your car’s tires will hydroplane or float on top of the water causing a loss of control and possibly an accident.  Test all of your tires at the same time and once you’ve decided when to replace the tires make sure they are all replaced at the same time.  Mismatched tires won’t give you the adequate safety or performance levels that a matched pair of tires will.  If you see wires on your tread or notice wear on the sidewalls of the tire, don’t waste time with a penny, replace the tires!  If any of this checklist gives you a headache just thinking about it.  Have your auto repair shop do the work for you, that’s their job!

Why & When Should I Rotate My Tires?

by Leave a Comment

In order to get the maximum life out of  your tires, it is important that you rotate them regularly.  Rotating tires evens out the wear and when it is properly done, it can extend the life of your tires, improve gas mileage and enables your car to handle sudden stops and turns properly.

The best indicator that it is time to rotate your tires is uneven tread wear.  When you look closely at your tires is the inside or outside of one tire showing more wear than another? Uneven tread wear is unavoidable because the weight of a car isn’t evenly distributed to all four corners.  Most engines are in the front and since the engine is the heaviest thing in the car, the front tires carry more weight.  That means that your front tires will wear out faster than the rear tires.  By rotating the tires, you are moving each tire to a different corner of the car so each tire is worn more evenly.  Also if you notice that your car begins to handle poorly when braking.  Or your tire traction is poor in slippery or wet road conditions, these are also indicators that your tires should be rotated.

A general rule of thumb for rotating tires is every 3,000 to 7,000 miles.  You can also pair tire rotation with oil changes and rotate tires every other oil change, if you change your oil every 3,000 miles.  Your car’s manufacturer manual will also have recommended times to rotate tires.  Maintaining a log or spreadsheet of when you perform tire rotations will help keep you up to date and your car running smoothly.  Store the log in your glove compartment or garage for a quick handy reference.

How To Find the Best Tire Dealer in Colorado

by Leave a Comment

You are about to head out of town on a road trip vacation. You know it’s been a while since you’ve purchased new tires, and have started noticing your tires are looking old and worn. In order to keep your family safe, replace your tires before you head out of town.

How do you find the best tire dealer in Colorado? One that will give you honest advice, the best price, and give you quality customer care from beginning to end.

Do a little research.
Start online. The best tire dealers value their reputation and their business. They will spend the time and money on their business, and give you a sense of security when making your final selection. It’s always a bit stressful when you choose a company to work with, only to find they’ve shut down a few weeks after you’ve been in. A reputable tire dealer will be in business for the long haul.

Don’t always choose a big box store.
We’ve all heard the big box names that have multiple locations around the country. They focus on one thing, and one thing only. While they may seem to have the best price upfront, they may actually have hidden costs. Ask questions. What guarantees do they have? Do they offer extra services, such as tire rotations or free repairs?

Support your neighborhood location.
Sometimes it’s nice to build friendships within your local community. While chain stores can have low prices, they may also have a huge fluctuation in employment. Meaning you’ll never get the same person when you visit a location. Not so with a neighborhood tire dealer. In many cases you’ll be dealing with the owner. Not only can he offer you advice and great service today, but he’ll also remember you on your second, third and fourth visit. And that can bring you peace of mind that you’re getting honest service, no matter how large or small your problem.
