The Common Causes of Uneven Tire Wear

When was the last time you looked at the tread on your tires? Do they have uneven tire wear? You walk past your tires several times a day, but many people don’t take a few seconds to look at them. Tires wear quickly, especially if you buy the economical varieties, and if your tires wear unevenly, it can be dangerous for you to drive.

If you know anything about music, you know that three parts make perfect harmony. Your vehicle is like music; the suspension, brakes, and tires must work harmoniously to keep things running smoothly. Tire wear happens over time, but there are many reasons why your tires may wear prematurely and unevenly.

Understanding the Contact Patch

Your vehicle requires a specific size tire. If you put the wrong size on your car, it can affect many things. Tires are designed with a contact patch specifically for your automobile’s weight and size, which is the area that makes contact with the roadway. It’s shocking when you consider that this area of your tire is no more significant than the palm of a large hand.

If your tires begin to wear unevenly, it’s dangerous as it reduces your ability to control the car effectively. These uneven spots will reduce the amount of steering control you have over your vehicle, and it will increase your stopping distance. It would help if you have your tires checked at every oil change, but it’s wise to look at them periodically to ensure everything looks good.

Common Reasons for Uneven Wear

We often see vehicles entering the shop with excessive outer or inner wear on the tires. We also see cupping, center wear, and feathering too. While you may not understand all these terms, you must familiarize yourself with the types of uneven wear and what causes them. Here are the most observed reasons for uneven wear.

1. Over Inflated Tires

Many folks think putting more air in the tire is always better than not having enough. Too much air will cause your ride to be rough and reduce your braking and steering abilities. When there’s excessive pressure in the tires, it causes your tires to receive impact damage and wear down faster.

2. Under Inflated Tires

When there’s not enough air in your tires, it will cause wear on the outer edges. Driving with low tire pressure causes the sidewalls to overheat due to too much flexing. Additionally, it will mess with your fuel economy.

3. Wheel Alignment Problems

Alignment issues will eat the tires right off your automobile. It causes damage to the inner and outer edges and will completely ruin the tires. If you notice your car pulling to one side, a vibrating steering wheel, or a vehicle that’s hard to control on the roads, your alignment is likely out of whack.

4. Worn Shock Absorbers or Struts

Struts help absorb the shock your vehicle feels on life’s highways. When the struts or shock absorbers wear down, the tires will cup. Some folks call it scalloping, but it’s worn sections that are patchy within the tires, which give it a dip or cupping effect.

Putting new tires on the car will do little if you have alignment issues and need struts. You must ensure you get to the root cause before buying new tires.

5. Reckless Driving

Some folks don’t know how to take the corners properly to avoid tire damage. If you’re swinging around corners at high speeds, it can cause your tire tread to feather. If you have feathering on your tires, you’ll likely notice your tires are noisy before you see any visual problems with them.

When looking at the tire, observe any tread that’s angled or goes in a diagonal pattern. It’s sometimes easier to feel a feathering issue than to see it, so run your hand across the tires.

Ways to Prevent Uneven Tire Wear

Tires are a considerable investment. Thankfully, there are many things that you can do to avoid premature wear. Changing a few of your driving habits can significantly impact your tire wear. Try to observe the following items:

•Stay off the curbs, even though it’s hard on those sharp turns.
•Have your alignment checked annually.
