The Cooper Discoverer STT Pro All-Season 35X12.50R22LT 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 had high hopes for these Cooper STT Pro tires based on the reviews, but sadly they've let me down. They arrived with some scuffs, and it took longer than expected to receive them. They work okay but not as great as others claim. Disappointed.

Decent tires, but a bit noisy
I’ve been using these Cooper tires for a few weeks now. They handle well on pavement, but I’ve noticed they are a bit louder than I expected when driving at highway speeds. Still, they perform well in wet conditions which is what I needed. Not perfect, but not bad either!

Sturdy and reliable for towing
Using the Cooper Discoverer STT Pro tires for towing my boat, and they perform really well. The stability and handling are solid, and I feel secure driving with my trailer. Definitely buying them again when it’s time to replace!

Build quality feels solid and reliable so far
After installing these control arms, I noticed a clear improvement in stability and ride comfort. The steering feels tighter and the car handles bumps much better than before.

Good but installation was tricky
The tires are great overall, but I had a hard time during installation. The size 35x12.50R22LT was a bit tricky to fit on my rims, but once on, they work as promised. They’ve got great traction in all weather, just plan for some installation time!
