Mud-Terrain Authority. Cooper Discoverer STT Pro Mud-Terrain Tire fits wheels requiring 38x15.50R20 tires and delivers relentless, all-season off-road traction with composed on-road manners when the pavement returns. Built to meet or exceed industry-leading safety and quality standards, it’s engineered to withstand rigorous running and punishing weather so your vehicle stays confident across mud, rock, sand, and rainy highway stretches.

Construction and Appearance. A non-directional tread style uses large, staggered lugs, deep voids, and strategic stone-ejector features to claw through loose terrain while shedding debris that can sap grip. Reinforced carcass geometry helps stabilize the contact patch under load, and advanced rubber compounds resist cuts, chips, and heat build-up for durability. Every tire is fabricated in a state-of-the-art facility and developed with strict attention to detail to ensure consistent performance and a purposeful, aggressive sidewall aesthetic once mounted.

Installation. Intended for a straightforward installation procedure, this tire mounts using standard equipment with no drilling, modification, or cutting required. Professional mounting and dynamic balancing are recommended to ensure precise bead seating, even wear, and smooth road manners; afterwards, verify pressures, schedule a fresh alignment, and follow regular rotation intervals to sustain predictable handling and long tread life on your vehicle.

Warranty. Paired with a standard limited warranty coverage, the tire is protected against defects in materials and workmanship for added peace of mind. The coverage underscores the robust construction, quality control, and validation testing that go into each unit, so you can expect dependable service through varied seasons and terrain.

Application. This Cooper Discoverer STT Pro Mud-Terrain Tire fits wheels requiring 38x15.50R20 tires. Choosing this tire enhances off-road bite, improves self-cleaning in muddy conditions, and lends a bold, capable stance that helps your vehicle feel prepared for everything from trail days to stormy commutes.
