Nitto makes some noise with quiet off-road tire
Nitto Tire U.S.A. Inc.'s new off-road tire blends some of the off-road performance of the Mud Grappler with the on-road comfort and quiet ride of the Terra Grappler.
The result is the Nitto Trail Grappler M/T. According to Staff Engineer Anthony Lee, the tire "is engineered to be a trail-ready tire without compromising on-road comfort and performance. We used advanced computer design and analysis to test the functionality of multiple designs before building the tire."
For off-road performance, the sidewall combines three-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. When navigating tough terrain, the balanced void ratio and stone ejectors help clear debris from the tread to provide continuous traction.
For on-road comfort, Nitto’s engineers used advanced sound analysis equipment when developing the Trail Grappler M/T to reduce 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. On the outer shoulder block the reinforced grooves maintain block stiffness to further extend the life of the tire.
The Trail Grappler M/T will be available in September 2009. Initially, popular sizes for full-sized trucks, Jeeps and SUVs will be introduced; they will range from 32 to 37 inches in overall diameter:
* LT285/70R16 E 125/122P;
* LT295/70R17 E 121/118P and 35x12.50R17LT E 121Q;
* LT285/65R18 E 125/122Q, LT295/70R18 E 129/126Q and 35x12.50R18LT E 123Q;
* LT295/55R20 E 123/120Q, LT295/65R20 E 129/126Q, LT305/55R20 E 121/118Q, 35x12.50R20LT E 121Q and 37x12.50R20 LT E 126Q.
