Our flagship mud terrain tire, the Razr MT was engineered with know-how gained from Maxxis' involvement in off-road racing. The Razr MT features a new off-road compound with new chemical fillers for maximum tear and chip resistance as well as tread life. Innovative armor sidewall design maximizes sidewall traction and puncture resistance, while the new dual-core body-ply technology packs additional casing strength for superior durability and toughness.
