How Often Should You Replace Your Tires?
May 4, 2026
Tires last 3 to 5 years or 25,000 to 50,000 miles for standard all-season tires, though some premium tires are rated for 60,000-80,000 miles. But mileage isn't the only factor... tires degrade from age regardless of how much you drive. A tire that's been sitting in a garage for 6 years is unsafe even if it has full tread.
The Two Clocks: Mileage and Age
Tires wear from two things: use (mileage) and time (age). Whichever limit you hit first wins.
Mileage: most all-season tires are designed for 40,000-60,000 miles. Performance tires use softer rubber and wear faster (20,000-40,000 miles). Truck/SUV tires vary widely (40,000-80,000 miles depending on type).
Age: regardless of tread remaining, tires should be replaced at 6 years old and absolutely must be replaced at 10 years. Rubber compounds dry out, crack, and lose elasticity from UV exposure and oxidation. A 10-year-old tire with perfect tread is a blowout waiting to happen.
The Penny Test (Check Your Tread)
Insert a penny into the tread groove with Lincoln's head pointing down. If you can see the top of Lincoln's head, the tread is at or below 2/32"... the legal minimum and the point where wet traction is seriously compromised.
A better threshold: replace at 4/32" if you drive in rain or snow. At 4/32", wet braking distance increases dramatically compared to new tires. The penny test catches the legal limit, but the quarter test (insert a quarter... if you can see the top of Washington's head, you're at 4/32") catches the safety limit.
Check tread in multiple spots across the tire and on all four tires. Uneven wear indicates alignment or suspension problems that should be fixed before you put new tires on.
Signs You Need New Tires Now
Visible tread wear indicators (the flat bars between tread blocks are flush with the tread surface).
Cracks in the sidewall (sign of age-related rubber degradation).
Bulges or blisters on the sidewall (internal structural damage... this tire can blow out at any time).
Vibration at highway speeds that wasn't there before (possible internal belt separation).
The car hydroplanes easily in rain (worn tread can't channel water away from the contact patch).
Any of these mean replace immediately, regardless of mileage or age.
How to Make Tires Last Longer
Rotate tires every 5,000-7,500 miles (every other oil change). Front tires wear faster on FWD vehicles, rear tires wear faster on RWD. Rotation evens out the wear and gets you thousands of extra miles.
Check tire pressure monthly. Under-inflated tires wear the edges faster and reduce fuel economy by 1-3%. Over-inflated tires wear the center. The correct pressure is on the sticker inside the driver's door jamb, not on the tire sidewall (that's the maximum).
Get an alignment check annually or whenever you hit a significant pothole. Misalignment eats through tires unevenly and can halve their lifespan.
Replace all four tires at once if possible. Mismatched tires (different tread depths) cause handling and stability issues, especially in AWD vehicles where different circumferences stress the drivetrain.
