How to Establish Skid Steer Tire Sizes for Your Machine

Skid steer tire sizes are read: TIRE DIAMETER x TIRE WIDTH – RIM DIAMETER

For example, the popular skid steer tire size 33x12-20 has a tire diameter (or height) of 33", a width of 12" across the tread, and a rim diameter of 20". The 33x12-20 replaces the pneumatic tire size 12-16.5.
