What 20.5x8.00-10 means

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

  • 20.5Overall diameterThe tire stands about 20.5 inches tall when inflated and unloaded.
  • 8.00Section widthAbout 8 inches across the widest part of the tire.
  • –ConstructionBias-ply. The plies run diagonally, which gives a stiff, tough sidewall.
  • 10Wheel diameterFits a 10-inch wheel. This is the number that has to match your rim exactly.

Also written as

The same tire is cross-referenced as 205/65-10. If that's what's on your old tire or your paperwork, you're in the right place.

Size is only half the answer

Two 20.5x8.00-10 tires can be rated for very different weights. Load range (B, C, D, E and up) sets how much each tire can carry at its rated pressure, and on a trailer that number matters as much as the size does. Your trailer's certification label, usually on the front left of the frame, lists the size and load range it was built for. Bring us that label, your paperwork or the old tire and we'll match the load range to what you actually tow.

Commonly used on: utility trailers, small equipment trailers.

Specialty Trailer (ST) tires are built with stiffer sidewalls for towing loads and are rated differently than passenger tires, so they aren't interchangeable just because the numbers look similar. Your trailer's certification label lists the size and load range it was built for. Matching it is what keeps the load capacity you're supposed to have. Bring us the label or the old tire and we'll match it.

Yes. 20.5x8.00-10 and 205/65-10 are cross-references for the same tire, written in different notation systems. Trailer and equipment tires are often listed both ways, so don't worry if your paperwork and your sidewall don't look identical.
