Discoverer STT Pro

Built for drivers who need severe-duty traction and sidewall toughness, the Cooper Discoverer STT Pro is a mud-terrain tire made for trail rigs, heavy-duty pickups, and other LT applications that see real off-road use. The Cooper Discoverer STT Pro tires are a strong fit for shoppers at Ron Gordon’s Tire Pros who want confident grip in mud, rocks, ruts, and rough jobsite conditions.

Cooper’s design focuses on durability and control with Armor-Tek3 carcass protection, 3-2 inner tread ribs, large depth side biters, Flex Groove, and alternating mud scoops with asymmetrical scallops. Those features help support traction, steering response, and stability when the pavement ends. Available fitments in this lineup include 275/65-20, 275/70-18, 285/70-17, and 245/75-16, with load range E and select load range F options across the catalog.
