OVERVIEW: The GT Radial Champiro Touring A/S is a touring, all season tire manufactured for passenger vehicles. GT Radial offers a 60,000 mile tread wear warranty with this tire model.The tread pattern design increases the all weather traction. The full depth siping detail boosts the dry, wet and winter weather road gripping ability with additional biting edges to maintain a firm hold on the road surface. The wide circumferential grooves also increase the wet weather traction and actively resist hydroplaning by dispersing water and slush from below the tire's footprint. The enhanced hydroplaning resistance and exceptional all weather traction ensure a safer year round performance.The tread pattern features large shoulder blocks and a solid center rib that keeps the tire close to the road surface at all times. This upgrades the model's controllability and maneuvering ability greatly. The solid center rib boosts the steering responsiveness and driving stability. In this manner, the tire's structure is stabilized against the driving pressure, while the steering becomes quick and precise in its responsiveness to the driver's commands. The larger shoulder tread blocks enhance the cornering and maneuvering ability by increasing the number of biting edges that grip the road surface. The combination of these enhancements ensures a secure driving experience in all weather conditions.The tread design's variable pitch design offers a quiet and comfortable driving experience. The pitch sequence manages to negate the road noise while the tires are in motion. It creates a sound frequency that cancels out the road noise generated during the drive and decreases the road noise levels heard in the vehicle's cabin. The result is an enjoyable, road noise free drive.The Champiro Touring A/S was manufactured with a specially designed sidewall that manages to protect and guard the rim from accidental curb damage. 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.
