## Description

The Cooper Discoverer STT Pro All-Season 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: Amazing. - Quiet and rugged. I was super leiry of buying tires on line. These tires are amazing. Very little if any road noise. Went from 265 to 315. Felt very little loss of power. The difference on the trails were significant. These tires bite and release the mud better than I could have imagined. Absolutely love the look, agility, and off road capabilities. Would highly recommend. I have tried uploading a picture but it won't let me. Anywho. They are amazing
Review: Excellent purchase!! - Great tires! surprisingly quiet for this type of tire.

### ⭐⭐⭐⭐⭐ Excellent purchase!!

Great tires! surprisingly quiet for this type of tire.

### ⭐⭐⭐⭐⭐ This is my second set of these tires
*by J***N on October 12, 2023*

My first set of the Discovery STT Pro lasted approximately 42,000 miles and still had enough tread to go another year. I decided to swap out my old tires because they have been on my Jeep for almost 10 years and due to an alignment issue there was some cupping. The new tires are amazing. There is very little road noise and the Jeep handles very well. I think as these tires wear out the road noise will increase (I believe this has been typical of other tires I've had on my previous Jeep). Overall I am very happy with the previous tread life of these tires and impressed with their on-road performance.
