Bridgestone Battlecross X31 Rear Motorcycle Tire 100/90-19 57M

The Bridgestone Battlecross X31 Rear Motorcycle Tire 100/90-19 57M is a bias-construction off-road rear tire made in Japan and built around Bridgestone's Bunker Groove technology, which allows the casing to flex more through the tread area so that the lugs stay in better contact with the ground. That added flex is designed to improve traction in rough and loose terrain. This tire is not certified for use on public roads.

The size code 100/90-19 tells you the tire has a 100 mm section width, an aspect ratio of 90 percent of that width, and fits a 19-inch rim. The rim diameter must match your wheel exactly, and the full size code should match what is printed on the sidewall of the tire you are replacing. This tire carries a load index of 57 and a speed rating of M, which covers speeds up to 81 mph (130 km/h). Your machine's specification determines which load index and speed rating are required.
