Cooper Discoverer AT3 LT
Your truck needs a tire that can handle life’s many demands–and the Cooper Discoverer AT3 LT fits that bill.
With strong all-season traction, capable off-road performance, and extreme durability for towing and hauling, the Discoverer AT3 LT is versatile enough to do its duty in every season.
When the off-road calls, this tire is more than capable of handling dirt, mud, sand or gravel thanks to its stone-ejecting ledges and superior grip. And when you’re cruising city streets and highways, ride in surprising comfort thanks to its specialized noise-reducing grooves, all while enjoying long-lasting tread life thanks to its wear-resistant tread design.
Cooper Discoverer AT3 LT Features
- Haul heavy loads and prevent wear with Durable Tread™ Technology
- Experience excellent all-terrain traction with aggressive Secure-Grip™ tread pattern
- Get added durability with the cut- and chip-resistant compound and stone ejectors that prevent stone drilling
- Enjoy a quiet, comfortable ride for an all-terrain tire with Cooper’s Whisper Groove technology
Cooper Discoverer AT3 LT Treadwear and Warranty
Because you’re choosing Cooper, your purchase includes the manufacturer’s standard limited warranty, a free 45-day test drive, and a 60,000-mile treadwear protection.
But if you want the most robust protection available for your new Cooper LT tires, consider investing in our exclusive and industry-leading Certificates.
If you do, you get complete coverage and your new tires will be protected down to 3/32" of wear. And in the extremely unlikely event these tires sustain damage that can't be repaired, you'll get a brand new replacement Discoverer AT3 LT.
(You can add our Certificate coverage in the cart of your order).
Built to withstand off-road assaults and tough hauls, but designed for superior on-road handling, the Cooper Discoverer AT3 LT all-season tire makes the perfect new addition to your truck or SUV.

Tacoma
More quiet than my previous street tires. Smooth ride
Defender 90
Very good tires! So far so good.
F-150
There tires make my truck feel like something on the rear end is broken or, I have rear steering that has a mind of its own. It's worse while towing, the rear sway is so bad I no longer feel safe towing my travel trailer. I did not have this issue with my previous tires.

While towing, these tires make it feel like something in the rear end is broken. I have them inflated to towing pressures, but it's so bad I've canceled trips where I would be towing our travel trailer. I didn't have this feeling with my previous tires

Good dirt road and off road traction. Moderate rock retention.
