Features and Benefits

The Discoverer AT3 LT is an excellent blend of all-terrain and all-season tires. As an all-terrain tire, it provides superior grip and traction on rocky terrains, dirt, gravel, highways as well as suburban roads. As an all-season tire, it offers traction and grip in dry, wet, and light winter weather conditions. Let’s take a look at the various impressive features offered in this tire. Balanced on-road treadwear – The Discoverer AT3 LT features patented Even Wear Arc Technology that ensures balanced on-road treadwear and impressive handling throughout the tire’s service life. Lower noise levels – The Whisper Grooves Technology is another patented innovation from Cooper that provides a sound barrier and doesn’t let the airwaves accumulate in the footprint to provide a quieter and more pleasant ride. Impressive cut and chip resistance – This Cooper all-terrain tire is provided with Durable-Tread Technology that protects the tread from cuts and chips caused by rocks, gravel, and other sharp objects, thus enhancing the tire’s self-guarding ability. Optimum self-cleaning ability – The Discoverer AT3 LT is engineered for on- and off-road use in diverse weather conditions. Sometimes, it could be used on wet roads and likewise, sometimes it could be taken on mud, dirt, gravel, etc. Therefore, the tread of this tire features bigger gaps between the tread blocks that promote self-cleaning and provide superior traction and grip. Enhanced durability – This pickup tire is built to perform heavy-duty tasks and run through challenging terrains, therefore, Cooper has put in efforts to make it as durable as possible. Its internal structure has a dual-ply polyester casing and twin steel belts combined with a sturdy nylon ply. The durable construction lets the tire maintain its original shape even when it is used in aggressive conditions. Exceptional year-round grip and traction – The tire features a silica-rich tread compound and a 5-rib design that boosts the tire’s gripping ability in dry, wet, and light winter wet conditions. While the advanced silica compound keeps the tread flexible in light wintry conditions for a firm grip, the wider tread grooves evacuate water from the contact patch area and reduce the chances of hydroplaning for a surefooted grip. Additionally, the staggered tread blocks provide better biting ability on soft, loose, and uneven terrains for improved grip and traction. Limited tread life warranty coverage – Cooper offers a limited manufacturer tread life warranty coverage of 60,000 miles on purchase of the Discover AT3 LT.
