Cooper Discoverer STT Pro Tires

Product Info

Discoverer STT Pro

Built for drivers who want true mud-terrain traction without giving up everyday road usability, the Cooper Discoverer STT Pro is a serious option for off-road-focused trucks and SUVs. The Cooper Discoverer STT Pro tires combine aggressive tread design, heavy-duty construction, and trail-ready durability for drivers who spend time in mud, dirt, rock, and rough backroads.

At Gunnell's Tire & Auto, this lineup is centered on LT fitments for pickup and SUV applications, with popular choices including 265/70-17, 285/70-17, and 275/65-20. These sizes make sense for lifted trail builds, midsize off-road rigs, and heavy-duty pickups that need load-capable traction and stronger sidewall protection.

Key technology highlights include Armor-Tek3 3-ply carcass construction, 3-2 inner tread ribs, Mud Slinger 2.0 tread design, large side biter cleats, Flex Groove, and alternating mud scoops for better grip and self-cleaning performance in severe off-road terrain.
