Cooper Discoverer STT Pro Tires

Product Info

Discoverer STT Pro

Cooper built the Discoverer STT Pro for severe-duty traction and sidewall toughness, making it a strong fit for off-road-focused trucks and trail rigs at Discount Tire & Automotive Inc.. The Cooper Discoverer STT Pro tires are LT-only mud-terrain tires with 24 fitments, offering rugged options like 245/75-16, 265/70-17, and 285/70-17 for drivers who want confident bite in mud, rocks, and ruts.

Built for pickup trucks, heavy-duty pickups, and SUV builds that spend real time off pavement, this model emphasizes 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, stability, and durability when the route turns rough, while still giving the tire more controlled highway manners than many extreme mud tires.

If you are comparing fitments for a lifted build or work-ready rig, start with common sizes such as 275/65-20 and 275/70-18. Shop with Discount Tire & Automotive Inc. online, then use Schedule Appointment or Shop Tires to move forward.
