The Cooper Discoverer STT Pro All-Season 37X13.50R17LT 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.
I installed these Cooper Discoverer STT Pro tires on my truck for off-roading and I couldn't be happier. They're 37x13.50R17LT, which gives me fantastic grip on rocky terrain and mud. Plus, they look really rugged!

Packaging issues, but the tires are solid
Received my Cooper Discoverer STT Pro tires quickly, but one of the boxes was slightly damaged. Fortunately, the tires themselves were in perfect condition! They grip great on rocky paths, definitely worth it for my off-road adventures.

Good tires, but noisy on the highway
I got these Cooper STT Pro tires for my Jeep and they perform well off-road, but I do find them a bit noisy when I'm driving on the highway. The all-season aspect is nice, but I wish they had a little less road noise. Still, decent tires overall!

Impressive all-terrain performance
These tires are fantastic for all-season driving, especially since I live in a place with unpredictable weather. The 37-inch size gives my truck a nice lift, and they handle snow and rain like a champ! Really pleased with the purchase.

Disappointed after a few months
I wanted to love these tires, but after three months of use, one started losing air and I found a small puncture. I expected more durability from a 121Q rated tire. Not the experience I was hoping for.
