About this item

Product details

Before purchasing tires, make sure to use our Tire Finder to select the right fit for your vehicle.

Cooper introduces the Discoverer Stronghold AT. Strong and Durable, and backed by a 60,000 mile warranty, this tire will last until the job is done! Strategically designed tread lugs help to resist cracking, tearing, and rounding of the tread. Ledges between the lugs help prevent stones getting stuck in tread. The Stronghold is protected from demanding environments. A specialized rubber compound and wide lateral grooves help plow through water, providing maximum traction.

Solid Traction in Dirt and Gravel
Wide open grooves in the tread grab and release soft surfaces, while the narrower center grooves help to provide stability.

Strength that Lasts the Test of Time
Strong shoulder design features such as scooped tread edges, wide tread grooves, and sidewall hook pattern all help provide grip and traction for the life of the tire.

Great Snow Traction
Textured edges on the shoulders grab into snow to help provide traction in harsh winter conditions.

Three-Peak Mountain Snowflake Designation
Tires designed for use in severe snow conditions and meet specific snow performance test requirements.

COOPER TIRES

Great looking tires should last me a couple of years if no flats etc.. They ride quiet and impressed with how they handle the road.

Cooper Stronghold AT

Installed a set of 6 Cooper Stronghold AT's on my Ford F350 4x4 Dually about 14 months ago and I've put about 8K miles on them and so far they still look new. They have performed well in all conditions. I've logged about 3500 miles towing a large 5th wheel RV with no adverse issues. Highly recommend them.
