DUAL SIDEWALL DESIGNS Each Grappler has two sidewall designs so you can choose how your tires look. On the Mud Grappler, one side has lizard skin sidewall lugs and the other has plain sidewall lugs. Choose any line. AGGRESSIVE SIDEWALL LUGS The sidewall design is as important as the tread pattern for maximum off-road performance. The Nitto Mud Grappler mud terrain tire has one of the most aggressive and functional sidewall designs on the market. The massive side lugs provide additional biting edges, which is especially helpful in rocky terrain. The additional depth also provides punctured resistance. Leave mud in your wake. HIGH VOID RATIO The high void ratio between the tread blocks efficiently clears mud and dirt from the pattern to provide excellent traction in extreme terrain. Make it back every time. PUNCTURE RESISTANCE The three-ply polyester sidewall construction and high strength steel belt tread package improve puncture resistance. *By request/order.
