Cooper Discoverer STT Pro Mud Terrain Tire

The Cooper Discoverer STT Pro is a mud-terrain tire (also called an M/T or off-road light truck tire). It is built for Jeeps, SUVs and light trucks that see serious off-road use. The aggressive tread is designed to give traction in mud, gravel, rock, sand and loose terrain. It is also made to stay stable and fairly quiet on the pavement.

Key Features:

• Armor-Tek3 construction: a 3-ply carcass that helps resist punctures, cuts and impact damage.
• Aggressive mud-terrain tread: deep voids, wide circumferential grooves and alternating shoulder lugs help the tire dig in and clear mud.
• Mud scoops and release features: these help move mud out of the tread so the tire stays self-cleaning.
• Stone ejection: features that help prevent stones from lodging in the tread and extend tire life.
• Sidewall traction: shoulder cleats (side biters) and flex grooves add grip on rocks and help absorb impacts from rough pavement.
• Silica-enhanced compound: supports wet traction and tread life.
• On-road manners: the tread layout is designed to reduce road noise and improve stability and handling.

The Discoverer STT Pro is Cooper's most capable off-road tire. It suits drivers who want rugged traction and durability on the trail, plus daily-driving manners on the road. Each size is sold individually and comes with Cooper's limited warranty.
