Cooper Discoverer S/T Maxx 315/70R17

All Season

Light Truck

All Terrain

The Cooper Discoverer S/T Maxx is a all terrain, all season tire manufactured for light trucks. The tire promotes great all weather traction. The tread design increases its capability on off-road performance. The tread design maintains a clean footprint by eliminating mud, snow and rocks stuck between the tread elements. The Y-shaped tread block placement prevents irregular tread wear by evenly distributing the driving pressure along the tread area. This tread design also manages to lower the road noise levels heard during the drive. The Discoverer S/T Maxx has great durability with its reinforced structure that prevents deformation.

Features

Self-cleaning Tread

The stone ejectors, specialized groove walls and large grooves eliminate mud, snow and rocks from between the tread.

Longer Tread Life

The hybrid four-five rib pattern evenly distributes the driving pressure and prevents uneven tread wear formations.

Quiet Drive

The tread design's varying tread block placement lowers the road noise levels heard while the tires are in motion.

Rugged Terrain Tire

The tread design enables the model to conquer harsher soft, loose and uneven terrain surfaces with ease.

All Season Tire

The durable silica compound and tread design improves the dry, wet and winter weather road gripping capability.

Durability

The Armor-Tek3 carcass construction protects the tread area and the sidewall during the drive by keeping the optimal shape.
