## Description

The Cooper Discoverer STT Pro All-Season LT315/70R17 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: 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: Great price for 37's - I've been running the Cooper Discoverer Pro STT's for a while now and needed to replace 2 of my tires. desertcart had the best price on 37x12.50R17's I could find, plus I didn't have to pay a bunch for shipping. These tires are great! Not a ton of road noise and they hold up great while off roading.

### ⭐⭐⭐⭐⭐ Mean look for any off-road vehicle
*by J***N on May 29, 2025*

These are the best tires I have ever had. I’m on set number 3. They get beat up when I go wheeling but they have good grip and get the job done. I hate that prices have gone up, but they were worth it to me. I mounted them to my beadlocks myself in the garage and have not had to rebalance the wheels.
