## Description

The Cooper Discoverer STT Pro All-Season 35X12.50R20LT 121Q Tire is the most extreme all-season, off-road tire Cooper offers to date, providing remarkable off-road performance without sacrificing on-road traction. The Discoverer STT Pro tire delivers best-in-class off-road performance, empowering the extreme off-roader to take on the toughest challenges. Patented Armor Tek3 tire technology adds strength to the tire sidewall, providing increased resistance to damage while driving over boulders and uneven, tough terrain. The Discoverer STT Pro comes with rubber formulated to combat shredding and damage from stones and off-road obstacles. The ROCK CLIMBER SIDEWALL gets max traction to help conquer even the toughest obstacles with deep ‘Climber Cleats’ and Flex Grooves built into the side of the tire that grip jagged rocks and power through thick mud. The MUD SLINGERS 2.0 are deep, wide trenches with additional notches throughout the tread combine to give you more grip to power through and help continuously clear thick mud from the tire. The EARTH DIGGERS can tackle tricky terrain with large blocks with alternating mud scoops that forcefully dig into loose dirt, sand or sticky mud. The STONE ARMOR TECHNOLOGY provides the ultimate durability with channels, ridges, and edges designed to help defend against sharp rocks and debris while expelling lodged stones.

Review: Great Tires - Bought a set of 4 for my 2019 Nissan Pathfinder. The delivery was quick. They are exceptional. They look great on my car, and the ride is smooth without a lot of road noise coming from the tires. The 65,000 mile warranty is a comfort of knowing I have bought a quality tire. Definitely recommend

### ⭐⭐⭐⭐⭐ Great tyres, conveniently & quickly delivered!
*by B***R on 3 August 2018*

Needed new tyres for my LR Defender110...bought some other ones (no names!) from another company! They arrived WRONG SIZE..& it took 3 weeks for them to admit & collect & return payment. Amazon does give you "peace of mind" in that direction - and the tyres are really excellent! A good mix between off-road and road use...shame they are NOT winter-rated! Two years on...(2020) tyres are all good, hard cornering on a wet road they'll slide - but predictably! Good in winter as well - though not EU winter-rated! Wear after 35000Km is very acceptable. Use off road is excellent, fantastic grip (shattered half-shaft actually!). Recommended buy especially if you do any off road/mud travelling
