Nitto Terra Grappler G2 A/T. FEATURES AND BENEFITS: All terrain traction; All weather traction; Lengthened tread life; Enhanced controllability; Reduced on-road noise levels; . OVERVIEW: The Nitto Terra Grappler G2 A/Tis an all terrain, all season tire manufactured for SUVs and light trucks. Nitto offers a 50,000 mile treadwear warranty with the light truck sizes and a 65,000 mile treadwear warranty with the SUV sizes of this tire model.The tire ensures first-rate all weather traction. The tread pattern design and the all season tire compound manage to firmly grip the road surface in dry, wet and winter weather. The tread design features large tread blocks, wide grooves and a full depth siping detail located on all tread blocks. This combination enhances the tire's road and terrain gripping ability through the year. The siping detail enhances the wet and winter weather traction by promoting additional biting edges. The compound maintains the tire's flexible traction all year round, even in colder temperatures. The wide grooves prevent hydroplaning by dispersing water and slush from below the tire's footprint. As a result, the model is safer to use in all conditions.The model's tread pattern and the durable construction enhance the model's on- and off-road performing capability. The tread elements firmly grip the road and terrain surface, making the tire's usability more versatile. The large tread elements enhance the tire's performing capability on soft, loose and uneven terrain surfaces as the large tread blocks, wide grooves, open shoulder pattern and staggered shoulder lugs and optimal sidewall tread design firmly grip the terrain surface. This tread design enhances the tire's capability on off-road terrains, even in deep sand and on loose dirt. The staggered tread elements and wide grooves maintain a clean footprint and prevent stone retention. They actively eliminate mud and snow and eject rocks stuck between the tread elements to avoid the footprint from being blocked from its contact with the terrain and road surface.The tread design features special reinforced coupling joints, that are located between the shoulder and center tread blocks. They manage to stabilize these tread elements and effectively resist tread flexing. In this manner, the tire not only boosts its tread life, but also increases its controllability. The prevention of tread flexing enables the tread area to evenly distribute the driving pressure. The equally spread out forces of acceleration, cornering and braking lengthen the tread life and the tire's usability. The stabilized tread elements also improve the steering responsiveness and driving stability as they do not wander while the tires are in motion. This improves the steering response time and accuracy to the driver's instructions and it stabilizes the structure against the driving pressure affecting it. The extended tread life and better control over the tires ensures the stronger performance.The Terra Grappler G2 A/T offers a quiet drive. The tread design features a variable pitch sequence that lowers the road and tread pattern noise heard while the tires are driven on-road. In such instances, the variable pitch creates a sound frequency that negates the sound waves generated while the tires are in motion. As a result, the road and tread pattern noise does not reach and is not heard in the vehicle's cabin, promoting a quiet and enjoyable driving experience. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
