Description

Built with durability in mind, the Cooper Discoverer Stronghold AT SUV and Truck Tires tackle difficult terrain to help your vehicle get the job done. It outperforms the Toyo Open Country A/T III in dirt and wet road handling, and when stopping on snow covered roads. Tough jobs demand tough tires, and the Stronghold AT delivers the traction you need when it matters most. Wide open grooves in the tread grab and release soft surfaces, while Cooper’s 3D-sipe technology helps to provide stability. This all-terrain tire provides grip and traction for the life of the tire. These tires resist cracking, tearing, and rounding of the tread, and prevent stones from getting stuck in the tread. Textured edges on the shoulders of the truck and SUV tire grab into snow to help provide traction in harsh winter conditions. The Cooper Discoverer Stronghold AT is protected by a 60,000 Miles Limited Treadwear Warranty. Cooper Tires offers a 45-Day Test Drive to test out your new tires. We’ve spent over a century building quality tires that are made to last. Incredible performance, reliable safety, and a price that won’t break the bank. That’s what you can expect from a Cooper Tire. Based on internal testing comparing Cooper Discoverer Stronghold AT (LT275/65R18) to Toyo Open Country A/T III (LT275/65R18) on a 2020 Chevrolet Silverado 2500 HD. Actual results may vary.

  • Great snow and ice performance
Size: 275/55R20
Amazing traction on snow and ice, gives full confidence in poor conditions. Haven't been able to test them in the rain but I have full confidence they will perform great. Very low noise on dry pavement no more than a regular street tire. Primarily bought for winter and I'm very happy with there performance and have a 60,000 mile warranty. ... show more

  • Great tires
Size: 275/70R17
Great tires. Never get flats with these. Never hydroplane. Lasts at least 60k miles with rotation every 10k miles. I'll get 80k miles from these.

  • Do not recommend vibrate and loud!
Size: 245/75R17
Very disappointed with these. Bought a set for a 2022 F250 and a 2023 F250. Cooper is a great brand and MADE IN USA is a plus. Always try to buy domestic if it's possible. I have had phenomenal results with the Cooper At3 XLT tires very smooth and quiet. Ordered the Stronghold AT for a slightly different look and a bit more aggressive tread. These ride and sound like a BIAS Ply Mud Tire. They are horrible and vibrate my teeth at certain speeds. I have contacted Cooper hoping they will do the right thing and let me exchange these for AT3's. ... show more

  • Great Tires
Size: 245/75R17
I first bought a set of these tires for my 2017 Ram. They ride great and traction in rain and snow is excellent. Noise is very minimal on my Ram for the deep tread. So I just received a set for my 2023 Jeep. Can’t wait to get these installed and see the difference in handling and control.
