The all-new Trail Grappler M/T blends some of the off-road performance of the Mud Grappler with the on-road comfort of the Terra Grappler to create a tire that is both aggressive and quiet. For off-road performance, the sidewall combines a 3-ply high turn-up construction with a thick rubber compound that cushions the tire and helps prevent punctures. On the tread surface, the blocks are configured to provide additional biting edges that command lateral stability and enhance forward traction. For on-road comfort, Nitto's engineers used advanced sound analysis equipment to reduce the noise levels commonly associated with off-road tires. The internal construction and tread design also help optimize tread life. Two wide steel belts provide a stable base for the tire and increase tread strength. This advanced construction provides optimal uniformity and reduces irregular wear.
