What 400/75-28 means

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

  • 400Section width400 mm (about 15.7 in) across the widest part of the tire.
  • 75Aspect ratioThe sidewall height is 75% of the section width. A lower number means a shorter sidewall.
  • –ConstructionBias-ply. The plies run diagonally, which gives a stiff, tough sidewall.
  • 28Wheel diameterFits a 28-inch wheel. This is the number that has to match your rim exactly.

Size is only half the answer

Two 400/75-28 tires can be built for very different work. Ply or star rating sets how much load each tire carries, and the tread code (R-4 industrial, L-2 traction, L-3 rock and so on) sets the ground it's built for. Tell us the machine and the work it does, and we'll match the tire to the job, not just the numbers.

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.

400/75-28 questions, answered

400: 400 mm (about 15.7 in) across the widest part of the tire. 75: The sidewall height is 75% of the section width. A lower number means a shorter sidewall. –: Bias-ply. The plies run diagonally, which gives a stiff, tough sidewall. 28: Fits a 28-inch wheel. This is the number that has to match your rim exactly. Altogether that works out to roughly 51.6 inches of overall diameter.

The size has to match, but so do the ply or star rating and the tread. A machine working pavement and concrete wants a different tread than one in mud or a gravel pit, even in the same size. Tell us the machine and what it works on and we'll steer you to the right tire.

We carry 370/75-28 in the same 28-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.
