## Description

The Cooper Discoverer STT Pro All-Season LT305/60R18 126/123Q 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: Cooper sst tires are legit. - I always used to use Dick Cepek tires until I bought my first set of coopers 2 years back. Now I always use Coopers on all 3 of my trucks. The SST,s are not noisy and handle perfectly on my f250 super duty , I love them for all my driving needs. They look aggressively awesome 10/10
Review: Great tires - These are really great tires, great traction, they wear great, they will make your vehicle stand out from the rest. They are a bit pricey. You get what you pay for though. They are a bit noisy on the highway, but the benefits out way a little noise. I recommend these tires 100%.

### ⭐⭐⭐⭐⭐ Great tires
*by B***N on July 17, 2023*

These are really great tires, great traction, they wear great, they will make your vehicle stand out from the rest. They are a bit pricey. You get what you pay for though. They are a bit noisy on the highway, but the benefits out way a little noise. I recommend these tires 100%.

### ⭐⭐⭐⭐⭐ Great tire so far
*by 2***B on February 2, 2016*

Great tire so far. Tread wear is good so far. I drove from Colorado to PA and back on these at high speeds and no issues. They make noise but they are not that loud. If tire noise bothers you, MT tires are probably not for you because these are the same (noise wise) as Cooper S/T Maxx's I have had on my truck prior to them. Love these tires, EXCEPT for they do kick up a lot more stones/debris and will chip your body paint around the tires. So get some mud flaps or 3M body protection film. I am going to get some 3M body protection film custom cut for the body style of my truck in these areas and continue running these tires.
