Cooper Discoverer AT3 XLT


The Cooper Discoverer AT3 XLT: the dark horse on a hot streak. The off-road dynamo with on-road manners. This Discoverer AT3 is Cooper's long-wearing, hard-charging flagship all-terrain tire built for those looking to get more from their truck, SUV or CUV when it matters most.

Cooper Discoverer AT3 XLT Features

The Cooper Discoverer AT3 XLT lays down all-season traction, aggressive off-road performance and durability for towing and hauling alongside its aggressive design and tread pattern.

But what makes the Cooper AT3 so good when the going gets tough?

It's all in the proprietary technology Cooper has packed in to the AT3 XLT, which includes:

  • Cooper's Durable Tread Technology, which helps you haul heavy loads over longer distances and brutal terrain—from a job-site payload to your weekend camping gear.
  • Its Secure-Grip tread pattern promotes all-terrain traction and protection from sharp rocks.
  • Even Wear Arc Technology, which maximizes treadwear and handling on paved roadways.
  • Cooper's Whisper Grooves create a sound buffer that minimizes road noise, vibration and harshness.

The Discoverer AT3 XLT also features other 4x4-based additions, such as stone ejecting ledges and rugged shoulders for enhanced grip when you might have to put your rig in 4-low over soft surfaces such as mud and sand as well as when you need to air down or lock your differential for bouldering.

Cooper Discoverer AT3 XLT Treadwear and Warranty

On top of its performance features, Cooper isn't selling the AT3 short on its manufacturer warranty.

At 60,000 miles of coverage for all LT-metric sizes of the AT3 XLT, Cooper is confident this Discoverer won't let you down no matter where your work or adventures take you.

But if you want the best protection for your new set of Cooper Discoverer AT3 XLT's available, our exclusive Certificates will cover them down to 3/32" of wear.

And in the extremely unlikely event you have a Cooper AT3 fail, you'll get a brand new one if it can't be repaired.

(You can add our Certificate coverage in the cart of your order.)

If performance and reliability combined with one of the more competitive price points in the all-terrain tire segment are what you're after, the Cooper Discoverer AT3 XLT might be the perfect fit.

      Too early to tell on tread life but based on everything I read, should last long time. Have driven skiing in snow few times already and very solid in snowy conditions with 4wd. We get a ton of rain and braking on wet roads seems very good. Really like the looks/profile.

        This is not my every day driver, it is a project vehicle that I have been reconditioning to be able to drive around on weekends.
