The Maxxis Creepy Crawler M8090 tire is a bias-ply extreme off-road tire designed to conquer the toughest terrains. When the tire is aired-down, the special bias construction allows the tire to flex and mold around obstacles. This is particularly important when rock crawling as you get more rubber in contact with the obstacle. The tire works great in varied terrain like sand, gravel, mud and hard-packed dirt terrain as well. Stone ejectors provide protection against tread cap damage from sharp rocks and the multi-edged knob design and sipe arrangement enhance traction on slippery surfaces. Large shoulder lugs and the added rubber in the sidewall provide unparalleled side bite in difficult off-road terrain. This bias ply tire is DOT-approved so can be used on your daily driver as well as your off-road rig.
