Cooper Discoverer Road+Trail AT. FEATURES AND BENEFITS: All terrain traction; Enhanced controllability; Upgraded driving durability; Quiet driving experience; . OVERVIEW: The Cooper Discoverer Road+Trail AT is an all terrain, all season tire made for SUVs. Cooper offers a 65,000 mile treadwear warranty with this model.The aggressive tread design and the stronger compound improve the tire's performance on all terrains. These elements work together to increase the tire's grip on soft, loose, and uneven surfaces. The large tread elements firmly grip the surface with extra biting edges and keep forward motion at all times. On the other hand, the special tread elements maintain a clean footprint by dispersing mud, snow, and rocks stuck between the tread elements. As a result, this combination guarantees a safe driving experience while resisting stone retention.Additionally, the tire's close surface contact enhances steering responsiveness and driving stability. The tire's steering response time is faster and more precise to the driver's commands, while the structure is secured against driving pressure. The large staggered blocks help the tire have better cornering. These elements significantly increase the tire's overall controllability and maneuvering. These elements enable the driver to have full control over the vehicle and guarantee a safe driving experience.The strengthened internal structure and the special silica compound improve the tire's on- and off-road performance. The strengthened internal structure does not allow the tire to deform under the load and driving pressure affecting it. At the same time, the special silica compound protects the tire against external damage, such as punctures, cuts, and tearing during the off-road ride.The Cooper Discoverer Road+Trail AT guarantees high driving comfort levels. The optimized tread elements manage to lower road and tread noise levels heard in the vehicle's cabin. The optimized footprint channels airwaves away, preventing them from coming into contact with the tread elements and generating noise. This reduced road noise levels enables the passenger's comfortable 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.
