The Cooper Discoverer STT Pro All-Season 37X13.50R18LT 124Q 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.
While the Cooper Discoverer STT Pro tires look tough and perform well off-road, I found they struggled a bit under heavy loads. My truck felt a bit unstable while hauling, which was disappointing. They’re decent for casual off-roaders, but I expected more durability for the price. Just be cautious if you’re frequently carrying heavy cargo.

Great off-road performance!
I recently switched to the Cooper Discoverer STT Pro tires for my truck, and wow, they’ve made a huge difference. The 37x13.50R18LT size provides excellent traction on rough terrains, and I love how aggressive the tread looks. I’ve taken them through mud and rocky paths, and they've handled it like a champ!

Disappointed with the wear
I had high hopes for the Cooper Discoverer STT Pro tires, but after a few months, the tread wore down faster than I expected, especially considering I don’t do extreme off-roading. They were great at first, but now I’m worried about their longevity. I wanted them to last longer for the price paid.

Stunning tread design!
These Cooper tires really caught my eye with their aggressive tread pattern. They look incredible on my lifted truck and definitely provide better grip in mud and sand. Installation was straightforward, and they hold air well. If you want something that makes a statement while off-roading, these are it!

Good all-around tire but noisy on highway
I’ve been using these Cooper tires for a couple of weeks now. They do great off-road and grip well in various conditions, but I was surprised at how much road noise they produce at high speeds. If you’re mostly off-roading, they’re fantastic, but for daily driving, be prepared for some sound. Still, I’d buy them again!
