## Description

The Cooper Discoverer STT Pro All-Season 38X15.50R20LT 128Q 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: Great tires - I have put 10,000 miles on these tires now and they drive amazing. The tread still looks the same the day I bought them. Highly recommend these tires.
Review: Awesome tires - Background: On my daily driver wrangler that mostly goes over NYC potholes I have only had these tires for a few months but so far they are awesome. They are pretty quiet for hybrid mud tires, work well in the rain and do not hurt my already terrible gas mileage lol. I haven’t used them in snow yet so I can’t comment on that but so far, they are doing everything I asked of them. I would also recommended to check out the specs on Cooper’s website on the size of the tires. I got 295/65/20 and I have yet to find a spare tire cover that fits...plan accordingly. Update 1/4/19 I went to Rausch Creek, Pa to do some off-roading and these tires are legit. At one point, I had a rock poking my tire with no issues, even waited there as my brother took a picture lol. Went on some green,blues, blacks, went through streams and mud with no problems. I probably could have done even tougher trails but I didn’t want to break anything. At the end of the day, I aired back up and was on my way. Again, I one hundred percent recommend. Looking forward to see how they are in the snow but I am sure they are great.

### ⭐⭐⭐⭐⭐ Satisfied
*by .***. on August 15, 2024*

They hum a bit at low speeds and it increases at highway speeds but to be expected with mud tires. I've heard many that were a lot louder. Good looking and seem to handle o.k. on wet pavement. Haven't done any serious off roading with them yet so will update later. They better work good @ $1971 for a set of 4 tires. Thought for that much it might include some stock in the Cooper co. LOL.
