The Nitto Mud Grappler is an extreme mud-terrain tire for lifted Jeeps, trucks and other trail-focused vehicles. It has an aggressive tread pattern meant for dirt, rocks, deep mud and other off-road obstacles.
The tread blocks are large and widely spaced. The high void ratio lets mud, dirt and loose debris escape instead of packing into the tire, which keeps the biting edges working. The blocks are arranged so part of the lugs stay in contact with the ground as the tire rotates. Large sidewall lugs add biting edges on rocks and ruts and can add protection against punctures and impacts. The sidewalls come in two designs: lizard-skin-style lugs on one side and a more traditional lug design on the other.
The sidewall is built with three plies of polyester, and the tread package uses a high-strength steel belt. This construction is designed to improve puncture resistance, including when running lower air pressures for added traction. The tire is made for off-road capability rather than quiet highway comfort. The tread produces noticeable road noise, and the heavy-duty build can ride firmer than an all-terrain or hybrid-terrain tire.
