Cooper Discoverer S/T Maxx Tires

Product Info

Discoverer S/T Maxx

Harsh gravel, rocky access roads, and loaded truck duty call for a tire built to resist damage, not just look aggressive. The Cooper Discoverer S/T Maxx tires give Gunnell's Tire & Auto shoppers a hard-use all-terrain option with a cut- and chip-resistant compound, a quieter rib-style layout than many mud-focused designs, and 24 active fitments including 235/80-17, 255/85-16, 265/70-17, and 265/70-18.

This lineup is especially relevant for LT replacements on heavy-duty pickups, midsize pickups, and body-on-frame SUVs that split time between pavement, towing, desert gravel, and rough job-site travel. Many current sizes are built in load range E, with select fitments carrying up to a 40,000-mile warranty, making this a practical choice for F-250-, Ram 2500-, Tacoma-, Wrangler-, Frontier-, and 4Runner-type use when size and load needs match.

Cooper supports that durability-first approach with Armor Tek3® construction, a Hybrid 4-5 Rib Design, Stone Ejector Ribs, and Non-Parallel Groove Walls to help reinforce sidewall and tread strength, resist stone retention, and promote more even wear.
