## 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: 3 Years and 50k Miles Later! - 3 Years and 50k Miles Later! Cause lets be honest that is what you want to know. I purchased a set of 4 - 295/70R18 On March 1st 2018 and they were installed March 5th the same year. Pros - *Amazing off road tires, especially if you air them down. They clean out better then tires 2x their price. Mud, Snow, Sand they have held up amazingly. * Road noise very limited the first couple years I have had less aggressive tires make way more noise when going down the highway. * Wear and Tare they have held up great. 50k miles 3 years and still have a good amount of tread on them. They actually shocked me usually 2 years is about all I get out of a really aggressive MT tire. These blew buy this expectation laughing. I actually just ordered a new set cause these are in that butter zone where I can make some cash back on resell. * Mount and Balancing. They mounted and balanced pretty easily for an aggressive MT tire. The balance line on the tire was pretty true and the Tech did not have to muck with them to much. Unlike some other MT's I have had that the Tech almost quit on me trying to get them balanced. Cons - * Road Noise 2.5 years - when they cut through about half the tread that noise starts to shine through the stippling in the tire that helps reduce this noise is pretty much gone at about half tire life and well yeah they start to howl. Now into year 3 and yeah they are border line obnoxious. Some people don't care about this howl, I tend to only cause I haul a boat and put on a lot of highway miles. However 2.5 years before they started howling is a .5 year longer then I thought the tires would last in whole. * Packed Snow and Ice - I am in ND land of the frozen nothingness. While Mud, Fresh Snow, and Sand mean nothing to these tires the lack of surface area has them singing a different tune. Packed Snow and Ice is a bit of a challenge for these tires. If you live in the north it is something you should note. However you should also know that most MT tires that have super aggressive tread suffer from this as it is a lack of surface area issue. * Rocks - again this is a con for all aggressive tires but these seem to be especially good at picking up rocks and stones and holding on to them for dear life. All in all I love these tires and like I said just ordered a new set. If you like a good looking tire that will hold up on the road and not leave you stranded off road. These are amazing tires.

### ⭐⭐⭐⭐⭐ 30,000 mile review
*by R***C on November 12, 2024*

I travel 60-70k miles a year. I've ran BFG's KO2's for many years, averaging around 80k before needing new ones. I've got 30k on these so far and I'm very pleased. They look aggressive and I like the stance of my truck better than I did with the BFG's. They balanced out easily & have a good ride with minimal road noise. They handle well & have good grip in the rain. If they continue to hold up for the next 50k as well as they have the first 30k, I'll have to consider making a permanent change.(After I try out the KO3's) As of right now I'm a fan!
