Cooper Discoverer AT3 4S 255/70R18, All Weather, All Terrain tires.

Features and Benefits: All weather traction; Enhanced controllability; All terrain traction; Cooper Discoverer AT3 4S TiresThe Cooper Discoverer AT3 4S is an all terrain, all season tire made for crossover vehicles and SUVs. Cooper offers a 65,000 mile treadwear warranty with new tires. The tire enhances the year round performance. The tread design and the all season compound work together to boost the dry, wet and winter weather grip on the road surface. The tread design with the sawtooth snow groove edges help to firmly grip the road surface at all times, optimizing the summer and winter weather traction. This pattern ensures the tire's ice and snow performing safety. The silica compound also allows the tire to maintain its rubber flexibility in versatile temperatures, increasing the all weather grip. The Aqua Vac Channel and the unique center grooves disperse water and slush from the footprint during the tire's on-road performance, offering a safer driving experience in wet weather situations. The model's optimized tread elements boost the on- and off-road traction. The five-rib pattern with the alternating tread block placement manages to optimize surface contact and grip on various soft, loose and uneven terrain surface conditions. This guarantees the tire's constant forward motion, preventing the tire's loss of traction when performing on soft dirt or through deeper mud. The tread design's zigzag sipes and staggered block pattern also maintain a clean footprint. These tread elements eliminate mud and snow from the footprint, optimizing the surface contact at all times. They also resist stone retention by ejecting rocks from the footprint, before they can drill into the casing. The Cooper Discoverer AT3 4S boosts the heavy-duty performing capability. The reinforced internal structure features a combination of polyester casing plies and twin steel belts which maintains the ideal tire shape throughout the drive. This prevents the tire from deforming under the pressure, which results in a better load capacity. As a result, the tire carries and handles heavy loads with ease. The better tire shape also optimizes the surface contact and increases the controllability. In this manner, the tire upgrades the steering responsiveness and the driving stability and enhances the driver's control over the vehicle. 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.
