Common questions

Which vehicles use 265/40R21 tires?

Any vehicle whose factory tire placard (driver's door jamb) or current tires read 265/40R21. The placard also gives the load index and speed rating to match. Not sure? Send us your year, make and model and we'll confirm the size.

Can I replace 265/40R21 with a different size?

Stay with the placard size unless a tire professional confirms an alternative — a different size changes speedometer accuracy, load capacity and clearance.

How many do I need?

Prices are per tire. Replace in pairs on the same axle, or all four for even handling and wear.
