When to Replace Your Car Tires for Safe Driving

How Long Should Tires Last?

A common question we hear is, "How long should tires last?" While the answer can vary depending on driving habits, vehicle type, and tire quality, most tires last between 25,000 and 50,000 miles, or around 6 years. Tires can degrade from age, exposure, and underuse, even if the tread looks okay.

At Pro Auto Repair in Marietta, we recommend scheduling regular tire inspections to evaluate wear patterns, damage, and aging, especially if it's been more than five years since your last set.

When to Replace Your Tires

So, how do you know when to replace your tires? Several warning signs indicate your tires may no longer be safe for driving, even if they haven't reached their mileage limit.

Tread Depth

Tread depth is one of the most critical factors in tire safety. Tires with less than 2/32 of an inch of tread are legally worn out and extremely unsafe, especially in wet conditions. Use the penny test: insert a penny into the tread with Lincoln's head facing down. If you can see all of Lincoln's head, it's time to replace your tires.

Uneven tread depth across the tire can indicate misaligned wheels or suspension problems, which Pro Auto Repair can diagnose and correct.

Tires Bulging

This is a serious red flag if you notice a bubble or bulge in the sidewall or tread area. Tires bulging usually means the tire's internal structure has failed—often due to a curb or pothole impact. This condition can cause a blowout anytime and requires immediate tire replacement.

Sidewall Cracks

Cracks in the sidewall may appear as small lines or slits. Sidewall cracks are often caused by aging, UV exposure, or under-inflation. These can lead to slow air loss or sudden tire failure. If you spot any cracking, have the tire inspected immediately by Pro Auto Repair professionals.

Common Causes of Uneven Tire Wear

Uneven tire wear can significantly reduce the lifespan of your tires and compromise your safety. Here are the most common causes of uneven tire wear our technicians see in Marietta:

• Overinflation: Tires overinflated wear more in the center, reducing grip and shortening lifespan. Always use a pressure gauge—don't guess.
• Underinflation: Underinflated tires tend to wear on the outer edges. They also generate more heat, which increases the risk of failure.
• Misaligned wheels: Misaligned suspension or steering components can cause tires to wear unevenly and prematurely.
• Bad shocks or struts: A bad shock absorber or worn struts lead to "cupping" wear, where tire tread develops high and low spots. You may feel vibrations when driving. Our team can diagnose and replace worn suspension parts to prevent further damage.

If you see signs of feathering, cupping, or inconsistent tread patterns, it's best to schedule a free tire inspection with us. We also check the steering and suspension systems, which are often the root cause of unusual wear.
