How Long Do Tires Last?

Tires last 40,000–60,000 miles OR 6 years from the manufacture date — whichever comes first. Old rubber is dangerous even with remaining tread.

Overview

Tire lifespan is governed by two independent clocks: mileage and time. Most tires are rated for 40,000–60,000 miles, but even low-mileage tires must be replaced by 6 years because rubber degrades chemically over time regardless of use. NHTSA and tire manufacturers agree that tires over 6 years old should be inspected by a professional, and most recommend replacement at 6–10 years regardless of remaining tread depth. The DOT date code on every tire's sidewall tells you the week and year of manufacture — a tire with 80% tread remaining but manufactured 7 years ago should still be replaced.

Signs It Is Time to Replace

Tread depth at or below 2/32 inch (penny test: Lincoln's head disappears = replace immediately)
Tread wear indicator bars visible — molded bars in the grooves are flush with the tread surface
Cracking or checking in the sidewall — rubber degradation from age or UV exposure
Bulge or blister in the sidewall — internal structural failure, immediate replacement needed
Vibration or pulling at highway speeds that cannot be corrected by rotation or balancing
Manufacture date over 6 years old regardless of visible tread condition

How to Make It Last Longer

Rotate tires every 5,000–7,500 miles to ensure even tread wear across all four tires
Check tire pressure monthly — underinflation is the leading cause of premature tire wear and failure
Balance tires when rotating to prevent vibration and uneven wear
Perform a front-end alignment when you notice the vehicle pulling or when you replace tires
Store spare tires away from UV exposure and heat — spare tires age even without use
Check tire pressure in cold weather — pressure drops about 1 PSI per 10°F temperature drop

What Affects Replacement Cost

Tire brand and type — budget, mid-range, performance, all-terrain
Vehicle size — larger wheels and larger diameter tires cost more per tire
Rim damage — bent or cracked rims require replacement before new tires can be mounted
Labor for mounting, balancing, and disposal of old tires

When to Replace

Replace tires when tread depth reaches 2/32 inch (immediate replacement), when the quarter test shows less than 4/32 inch of tread (recommended), or when the sidewall shows cracking or bulging. Replace by 6 years regardless of tread depth in hot climates (FL, TX, AZ where UV accelerates rubber degradation), and by 10 years in all climates. Never wait for a blowout — sidewall cracking or bulging indicates imminent failure.

Pro Tip

The DOT date code on your tire's sidewall tells you exactly when it was made. Find "DOT" on the sidewall, then look for the last 4 digits — they represent the week and year. "1523" means the 15th week of 2023. Check all four tires: they may have been made at different times, and a "new" tire you purchased may have been sitting in a warehouse for 2 years before you bought it.

Frequently Asked Questions

How long do tires last in miles?+

Most tires are rated for 40,000–60,000 miles. All-season tires for typical sedans average 50,000 miles. Performance tires designed for handling wear faster (25,000–40,000 miles). All-terrain truck tires last 40,000–60,000 miles depending on whether used on pavement or off-road. Climate and driving style significantly affect actual mileage achieved.

How do I know if my tires are safe?+

Check tread depth with a quarter: insert it into the tread groove with Washington's head down. If you can see the top of his head, you have less than 4/32 inch of tread — replace soon. Check sidewalls for cracking. Check the DOT date code — replace if over 6 years old. If any sidewall bulge is visible, stop driving and replace immediately.
