TBC Grand Spirit Touring L/X. FEATURES AND BENEFITS: Enhanced controllability; Longer lasting tread life; All weather traction; . OVERVIEW: The TBC Grand Spirit Touring L/X is a touring all season tire manufactured for passenger vehicles. It comes with some high performance, W speed rated sizes as well. TBC offers an 85,000 mile treadwear warranty with the T speed rated sizes, a 65,000 mile treadwear warranty with the H and V speed rated sizes and a 50,000 mile treadwear warranty with the W speed rated sizes.The tire's all weather controllability is improved. The asymmetric tread design maintains its constant road contact to upgrade the steering responsiveness and driving stability. In other words, the steering becomes faster and more accurate, while the structure is stabilized against the driving pressure affecting the model. The shoulder tread blocks, with the siping detail, heighten the number of biting edges which grip the road surface. This boosts the cornering and maneuvering capability and ensures the tire's excellent performance. The special lateral grooves of the shoulder design increase the braking capability by shortening the braking distance.The model's tread design and all season compound combined improve the all weather traction. The silica-infused compound keeps the tire's flexibility and effectively resists weather damage from harming the tread elements. The asymmetric tread's notches and siping details firmly grip the road surface and upgrade the dry, wet and winter weather performance. The circumferential grooves actively disperse water and slush from below the footprint. In this manner, they avoid hydroplaning and guarantee a secure wet and winter weather performing capability.The Grand Spirit Touring L/X offers a lengthened usability. The tread's full depth siping detail ensures the tire's excellent traction throughout its lifetime. The asymmetric tread's road contact manages to evenly distribute the forces of acceleration, cornering and braking across the tread area. The equally spread out driving pressure resists the formation of uneven tread wear on the tire's surface. The constant even wear and extended traction provide a longer lasting tread life and usability. 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.
