The Maxxis Trepador M8060 tire is a bias-ply M/T tire designed for off-road competition. The heavy-duty bias ply construction provides excellent durability and tread flex when needed. Tread Flex is important particularly in aired down rock crawling or mud bogging. It allows the tread to wrap around obstacles, which means more contact area and grip. The tread pattern is proven to be the most effective design for extreme off-road in variable terrains, and is very similar to the tread used in the radial version of the Trepador M8060.
