Cooper Tire & Rubber Co. says the CS5 Touring, a premium touring tire, is available in 78 sizes in Grand Touring (T-rated) and Ultra Touring (H-, V- and W-rated) tread options. The CS5 Grand Touring T-rated tire has an 80,000-mile tread wear warranty and is available in 30 sizes. The company says a new silica tread compound significantly improves the wet handling performance of the CS5 versus the tire it replaces, the CS4. The CS5 has four times more silica than the CS4, enabling improvements in wet traction without giving up tread wear. The company also optimized the overall profile and tread contact patch of the tire to improve ride quality and wear evenly and quietly.
