Cooper Discoverer A/T3 LT

Off-Road All-Terrain All Season Winter rated

Designed to haul heavy loads with less wear, the Discoverer AT3LT offers Durable-Tread Technologyâ„¢ to prevent shredding and withstand the ongoing assault of driving on dirt and gravel. A new cut- and chip-resistant compound significantly improves performance on sharp gravel and increases tread wear, and the shape of the tire has been engineered to balance pressure at the tire-to-road contact area, providing even on-road tread wear and superior handling. The Discoverer AT3LT features new Whisper Groovesâ„¢ to provide a sound barrier that reduces road noise as well as stone ejector ledges to easily discharge stone and gravel for enhanced durability. The tire is available in 21 sizes from 16-18 inch rim diameters.

Put coopers on a 2013 Triton, NEVER AGAIN. The under steer was dangerous. Swapped them for both Goodrich and toyo from other tritons and both of these were fine. With the coopers I could turn the steering wheel a quater turn and back while doing 60k, if I did that with the goodies or Tokyo’s I’d be in the trees.
Cooper tires didn’t help, the dealer took the tires back on goodwill.
NEVER will try coopers again

Used on 2010 Tundra. The ride when new is fantastic. These have great traction in all conditions. Did not travel other than dirt roads when off pavement.Had 3 sets on this truck. The first set lasted maybe 45k. The second set 35K. The set currently will be replaced next week with only 22k. Although I have been getting the new ones discounted due to warranty I will seek another brand, maybe Nokian Outpost AT.
