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.

  • Terrible service from Goodyear service center
Size: 275/65R20
The tires were shipped in a timely manner and exactly what I wanted. The issue was the recommended service center Goodyear Auto Service - De Witt, New York. They refused to install the tire huge inconveniences. Amazon did refund the installation charge.

  • Best tire ever
Size: 275/60R20
I absolutely love these tires. They are great in snow, awesome traction in rain or slush. Look amazing, balanced out real nice. I have about 5k on them. I m definitely buying another set when these are done.

  • Great Tires!
Size: 275/70R18
I got four of these. Delivery was fast using standard and the product did not disappoint. My pickup looks like a whole different pickup with these beasts on. Super hunky grips :)

  • 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

  • 2 thumbs up
Size: 225/75R16
Use for offroading. Work great on tree roots, mud, climbing over down tree trunks, ice and snow. 10 ply with no flats yet. Holding up to rev limiter speed on various terrain. Handle potholes with ease and puts out an impressive smoke show when I'm doing burnouts for immediate attention. I'm a WJ guy and don't care either, so... ... show more

  • Two weeks to receive all four.
Size: 315/70R17
Great tires but, because they took two weeks to receive, I will never buy from this company again. It's the responsibility of the seller to make sure prompt delivery, and they failed miserably.

  • Don’t expect the rebate!

Great tire, but my tire guy told me the rebate was a scam! He was right, don’t waste your time on waiting on your rebate it never showed up.. I guess I found a honest tire guy!!
