Tires expire even if the tread looks perfect. Find the DOT code on your sidewall, type the last 4 digits below, and get an instant verdict.
Under 6 Years
Within the recommended service life. Keep checking tread depth (1.6 mm legal minimum in most countries) and pressure monthly.
6–10 Years
Past the age most manufacturers recommend. Have a professional inspect for sidewall cracking — and budget for replacement now.
Over 10 Years
Beyond every manufacturer's absolute limit. Aged rubber fails without warning at speed — replace before your next drive.
Questions
Tire Age — FAQ
Where do I find the DOT code on my tire?
Look on the sidewall for lettering that starts with "DOT" followed by 8–13 characters. The date code is the LAST 4 digits — e.g. "2321" means week 23 of 2021. It may only be printed on one side of the tire, so check the inner sidewall too.
How old is too old for tires?
Most vehicle and tire manufacturers recommend replacement at 6 years from the manufacture date regardless of tread, and virtually all say never run tires older than 10 years. Rubber hardens and cracks with age even on a parked car — age, not just wear, causes blowouts.
My code only has 3 digits — what does that mean?
A 3-digit date code means the tire was made BEFORE the year 2000 (e.g. "329" = week 32 of 1999 or 1989). Any tire that old is dangerously past its life — replace it immediately.
Does tire age matter if the tread looks fine?
Yes. Oxidation makes the rubber compound brittle from the inside; the tread can look new while the casing is failing. Aged tires are a documented factor in high-speed blowout crashes, which is why used-car buyers should always check the date code.
