What 315/80R22.5 means

Every number on the sidewall is telling you something. Here's this one, decoded:

  • 315Section width315 mm (about 12.4 in) across the widest part of the tire.
  • 80Aspect ratioThe sidewall height is 80% of the section width. A lower number means a shorter sidewall.
  • RConstructionRadial. The body plies run across the tire. Radials generally run cooler at highway speed and wear more evenly.
  • 22.5Wheel diameterFits a 22.5-inch wheel. This is the number that has to match your rim exactly.

Size is only half the answer

Two 315/80R22.5 tires can be built for very different work. Load range and ply rating set how much each tire carries at its rated pressure, and tread design changes with axle position. A steer tire and a trailer tire in 315/80R22.5 are not the same purchase. Tell us the truck, the axle and how you run it, and we'll match the tire to the job.

Commonly used on: heavy-duty tractors, vocational and mixer trucks.

Other sizes on a 22.5" wheel

These share your rim diameter. Whether one of them will actually work depends on rim width, load range and fender clearance. Ask us before you switch.

315/80R22.5 questions, answered

315: 315 mm (about 12.4 in) across the widest part of the tire. 80: The sidewall height is 80% of the section width. A lower number means a shorter sidewall. R: Radial. The body plies run across the tire. Radials generally run cooler at highway speed and wear more evenly. 22.5: Fits a 22.5-inch wheel. This is the number that has to match your rim exactly. Altogether that works out to roughly 42.3 inches of overall diameter.

Yes. Steer, drive and trailer positions ask different things of a tire: steer tires are built for even wear and steering response, drive tires for traction, and trailer tires to take side loading and scrubbing. The same size is manufactured for all three, so tell us the axle when you call and we'll get the right tread pattern for the position rather than just the right numbers.

We carry 245/75R22.5, 255/70R22.5, 275/70R22.5, 275/80R22.5, 295/75R22.5, 295/80R22.5, 11R22.5, 385/65R22.5, 425/65R22.5, 445/50R22.5, 445/65R22.5 in the same 22.5-inch wheel diameter. Sharing a rim diameter doesn't guarantee a swap will work, though. Rim width, load range and clearance all have to line up. Call (320) 363-7246 and we'll tell you straight whether a change makes sense.

Stock moves, so the honest answer is to check. Send us the size through the availability request on this page or call (320) 363-7246. We'll tell you what we have on the shelf, what load ranges are available and how fast we can get anything we'd need to order.
