How do I know when I need new tires?
Answered by Super Tire & Muffler · Updated June 19, 2026
Short answer
You need new tires when the tread depth reaches 2/32 of an inch, when the built-in wear bars sit flush with the tread, or when you see cracking, bulges, or uneven wear. The quick check: put a penny in the tread upside down. If you can see all of Lincoln’s head, the tire is worn out and it is time to replace it.
The signs to watch for
Beyond low tread, replace tires that have sidewall cracks or bulges, repeated slow leaks, vibration that balancing will not fix, or uneven wear that points to an alignment or suspension problem. Age matters too: most tires should be replaced around six years regardless of tread, because the rubber hardens over time.
In Northeast Ohio winters, worn tires are especially risky. Grip drops off well before the tire is legally bald, so if you are sliding more than you used to, get the tread measured.
