How to Read ATV and Side-by-Side Tire Sizes

ATV and side-by-side tire sizes are written differently from truck and car sizes. Once you know what the three numbers mean, they are easy to read.

The three numbers

Take 27x9.00-12:

  • 27 is the overall height of the tire in inches.
  • 9.00 is the width of the tire in inches.
  • 12 is the rim diameter in inches.

The dash and the R

A dash before the rim size, as in 27x9.00-12, marks a bias-ply tire. An R in that spot, as in 30x10.00R15, marks a radial tire.

Ply rating

Our ATV tire listings show the ply rating in the name, such as 6 Ply or 8 Ply.

Check the front and the rear

Many machines run a narrower tire on the front than on the rear, so read the size off both before you order.
