Collection: 12R20 Tires

12R20 tires — roughly 41.6 in tall and 12.0 in wide overall. It is a commercial truck size.

We carry 12R20 in commercial truck, highway and all-season designs from MRF, Astro and Kapsen.

Available ratings in this size: load range J / L. Choose a load index and speed rating equal to or higher than what your vehicle's tire placard calls for.

Every tire is priced each and ships free to the lower 48 states (FedEx Ground, or truck freight for large commercial, farm and construction sizes), with 30-day returns on unmounted tires.

Common questions

Which vehicles use 12R20 tires?

Any vehicle whose factory tire placard (driver's door jamb) or current tires read 12R20. 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 12R20 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 (six on dual-rear trucks).
