Product Info

Nitto Mud Grappler 37x13.50R20E

The Nitto Mud Grappler 37x13.50R20E is an extreme-terrain radial tire for light trucks built for aggressive off-road traction. Its high-void tread helps clear loose material, while massive side lugs add biting edges in mud and uneven terrain.

A 3-ply polyester sidewall adds protection where rough terrain is most likely to make contact. Raised black lettering keeps the exterior styling focused on the Mud Grappler tread and sidewall design.
