AppointAre used tires safe to buy?
A used tire can be a reasonable buy if you check it carefully: it should be less than about six years old by its DOT date code, have plenty of tread left (4/32 inch or more is a common floor for used tires), no repairs near the shoulder or sidewall, and no bulges, cracks or cords showing. You usually cannot know how it was driven or stored, so for the front axle or a car used on highways, new tires are the safer choice.
Key facts
- Tire age is printed in the DOT code on the sidewall.
- Punctures repaired outside the tread area make a tire unsafe.
- Tires on the same axle should match in size and type.
Checklist before you pay
- DOT date code: how old is it? (reading the code)
- Tread depth: measure, do not guess (tread depth guide).
- Inside and outside sidewalls: no cuts, bulges or cracking.
- Inside the tire: ask whether it has been repaired, and where.
- Same size and load/speed rating as your car's placard (reading tire size).
