TBC Grand Prix Tour RS. FEATURES AND BENEFITS: All weather traction; Longer lasting tread life; Reduced road vibration levels; . OVERVIEW: The TBC Grand Prix Tour RS is a touring all season tire manufactured for passenger vehicles. TBC offers a 45,000 mile tread wear warranty with the W speed rated sizes, a 50,000 mile warranty with S, H and V speed rated sizes and a 60,000 mile warranty with T speed rated sizes of this tire model.The tire has excellent all weather traction and it grips the road well in dry, wet and winter conditions thanks to the special tread pattern. The cross channel and wide circumferential grooves disperse water from below the tire footprint and improve its hydroplaning resistance and wet weather traction. The tire's superb winter weather traction is the result of the full depth sipes. They not only lengthen the usability of the tire as they do not disappear with wear, but they also provide additional biting edges on ice and in snow, making the tire safer to use in all weather.This model offers a longer lasting tread life. The tread design spreads out the force of accelerating, cornering and braking across the tread area. As the driving pressure is equally distributed along the tread surface, it prevents an irregular wear pattern from forming on the tire. As a result, the tire's tread life lasts longer, as it is usable for a longer period of time.The center rib of the tread pattern maintains constant road contact. The better contact enhances the steering responsiveness and accuracy and promotes driving stability. The better stability allows the tire to perform to its utmost capability, while the steering responsiveness provides a quick and precise steering ability. The tire responds well to the driver's instructions, allowing them to confidently control the tire in the differing weather conditions.The Grand Prix Tour RS offers a comfortable driving experience. The maintained constant road contact makes the tire follow the road surface closely, which reduces the road vibrations felt in the cabin of the vehicle. This offers a more comfortable driving experience in all conditions. 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.
