How Do I Know If I Need New Tires?

Tires are designed to provide a vehicle with traction in order to prevent accidents. Without traction on your tires, your car would slide all over the road during natural elements such as rain, snow, and sleet. When driving through a puddle or snow, the tread creates channels that divert the water or snow away from the tires; allowing the tires to maintain traction and avoid hydroplaning.

What to look for:


Tires begin to bulge at the sides when they deflate or become weak. These bulges can cause a sudden blowout when driving on them.

Tread Wear

The best way to check for tread wear is the old-school penny trick. Stick a penny into the tread of your tire with Lincoln’s head pointing down. If you can still see the top of his head, your tread is very low and the tire should be changed. You can also look at the patterned grooves on your tires. If they look very worn down and have a smooth texture, they most likely need to be replaced.

Tire Pressure

Tires deflate at about one PSI per month. If your tires are deflating faster than 1 PSI a month, it could be the sign of a leak and should be fixed or changed immediately.


Tire pressure drops in very cold weather, and builds up in hot weather. When tires are exposed to extreme temperatures, the rubber begins to lose electricity and can cause cracking.


When a car begins to vibrate while driving, it could mean that there is something wrong with the tires. They could be misaligned, unbalanced, or have an internal problem with the tire itself. Misaligned tires can create irregular tread wear and cause them to wear out a lot faster.

Side Wall

Look for tracks or cuts in the sidewall of your tires. If there is any damage, it could possibly be a sign that your tire has a leak or is ready to blow out.


Tires should be changed every 6-10 years, depending on how often you use them. After 5 years, begin to check the tire pressure more frequently.

Make sure your tires are safe to drive on. If you happen to have a run-in with a blowout tire, contact Marblehead Collision!
