Kimpex Tire Chains for your 2009 Arctic Cat Thundercat 1000

The overall tire height when properly inflated. You can measure this by taking a soft tape measure around the circumference of the tire and divide that number by pi (3.14).

Width is measured in a straight line from the furthest point on one sidewall, across the tread, to the furthest point on the opposite sidewall.

Rim diameter is the diameter of the rim/wheel on which the tire will be mounted, in inches.
