Discoverer St Maxx

Drivers who regularly work in harsh terrain or demand dependable traction in unpredictable conditions will find the Cooper Discoverer S/T MAXX to be a standout option. Built for trucks and SUVs that see heavy use on gravel, rock, and rugged backroads, this tire blends aggressive all-terrain capability with the dependable manners needed for everyday paved driving. For shoppers putting together a complete tire set with the strength to tackle worksites and remote trails, the S/T MAXX delivers both toughness and versatility.

A key factor in its durability is Cooper’s Armor Tek3® construction, which reinforces the radial casing and sidewalls to better resist cuts, chips, and punctures. The tire’s unique hybrid 4–5 rib tread pattern helps control road noise while still supplying the bite needed on loose surfaces. Angled groove walls and a cut- and chip-resistant rubber compound further support long tread life, especially when regularly exposed to abrasive terrain. Stone ejector ribs are built into the tread to help prevent debris retention — a valuable advantage for maintaining traction and protecting the casing over time.

Despite its rugged build, the Discoverer S/T MAXX maintains stable on-road performance in dry, wet, and light winter conditions. With available sizes from 16" to 20", it suits a wide range of work trucks and overland-ready pickups. This tire offers the durability, traction, and year-round confidence that demanding drivers expect from a premium all-terrain design. Call 320-247-6160 for expert help.
