## Description

The Cooper Discoverer STT Pro All-Season LT305/70R16 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.

Review: Best tire Ive ever owned. And Ive owned ALOT. - So far they are fantastic. Ordered them in 265/75r16s and got exactly what I wanted. There is some road noise from them, but they are by far the quietest M/T I've ever had. I dont know why some site list these as a mud tire and some list them as all terrains, but let me clear the air. These are a mud tire that also perform well on the road. I've had them on dry pavement, wet pavement, 16in snow, deep mud, uphill climbs, and on rocks. Excellent performance on all around. The only think I really havn't tried yet is sand. In my opinion these are the best tires Cooper has ever came out with.
Review: If you’re looking for an aggressive looking & top notch off-road tire, look no further. - Love ‘em! I’ve had these on for about a year & a half, and have rotated them once. Completely even tread wear. They look spectacular with my black rims, very aggressive & rugged looking tire. I’ve had a ton of compliments since putting them on. I had been thinking about going with BF Goodrich or Nittos originally, SO glad I went with these instead. Great on the beach, in snow, and mud. Awesome tire, for a great price.

### ⭐⭐⭐⭐⭐ Good Looking, Quieter than expected
*by F***L on March 17, 2022*

So I ended up with a skinny pair of these 215 85r16. They came with this weird manual transmission swapped Caprice Station Wagon that I bought. The guy who built the car would use it to tow a dump trailer full of hay in his field. Car has an elocker whole 9. I bought it to tow but didn't really plan to take it offroad. So I had a nice pair of mud tires. I also have a 2000 Nissan Frontier 4x4 that was on bald Bridgestones, I decided to mount them on some Xterra wheels and bought a second pair for my Frontier. They look good. a little small, plenty of clearance, but I dig em. They ride good, grip good, what else can you ask for? I think these work out to a 30.4" or so. They rose the truck up a good bit. Will have to get this thing offroad asap
