## Description

The Cooper Discoverer STT Pro All-Season LT285/65R18 125Q 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: Cooper sst tires are legit. - I always used to use Dick Cepek tires until I bought my first set of coopers 2 years back. Now I always use Coopers on all 3 of my trucks. The SST,s are not noisy and handle perfectly on my f250 super duty , I love them for all my driving needs. They look aggressively awesome 10/10
Review: Great tires - These are really great tires, great traction, they wear great, they will make your vehicle stand out from the rest. They are a bit pricey. You get what you pay for though. They are a bit noisy on the highway, but the benefits out way a little noise. I recommend these tires 100%.

### ⭐⭐⭐⭐⭐ Awesome performing truck tire!
*by A***. on September 18, 2016*

Great tires in rain, mud and sand here in florida. Much quieter on pavement than i thought they would be. Very aggressive tread, i hope they wear slowly.. Update, 4.29.2018 Have been daily driving on these for 1.5 years! They wear slow, balance and rotate great still. Noise is very low at any speed. Still look amazing and my Tundra has never been stuck....ever WILL replace with exact same tire if they ever wear down enough to replace. Have well over 70% tread left
