Product Info

Discoverer Stronghold AT

Built for drivers who need dependable traction on pavement, gravel, and rougher jobsite surfaces, the Cooper Discoverer Stronghold AT is a smart all-terrain choice for heavy-duty trucks and SUVs. The Cooper Discoverer Stronghold AT tires are available at Gunnell's Tire & Auto in LT, load range E fitments such as 245/75-17, 265/70-17, and 265/70-18, with up to a 60,000-mile warranty for work-and-weekend versatility.

Designed for heavy-duty pickup and SUV use, this lineup is fully LT and load range E, making it a practical fit for vehicles like the Ram 2500. Every active size is snow-rated with the Three-Peak Mountain Snowflake designation, and Cooper backs the tire's mixed-surface confidence with scooped tread edges, wide tread grooves, a sidewall hook pattern, and ledges between tread lugs to help resist stone retention.

For Gunnell's Tire & Auto shoppers, this is a strong option if you want hauling confidence, gravel-road durability, and year-round traction without giving up everyday drivability. Use Shop Tires to compare available sizes, then book installation with Schedule Appointment, or protect your investment with Tire Rotation, TPMS Service, and a Wheel Alignment Check.
