Description

The Cooper Discoverer STT Pro All-Season 35X12.50R20LT 121Q 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.

Reviewed in the United States on December 3, 2024 by This is a nice unit it's easy to install however it's supposed to come with a bracket to mount the thermostat control on a wall and never includes it in the box it's would be much easier also if it had the knob control option as it can be a knoghmsre to run the extra wires for the wall mount control but this AC units runs smooth and quiet and has a great product warranty that's extendable for another 3 years the air deflector is not as nice as say domestic to control the air flow direction at the ceiling but it does the job none the less my customers like the system vans the attractive appearance of the unit on their rv roof and it's much lighter than a Coleman or recpro unit and most dometic AC units

Size: 31X10.50R15LT 109Q
Arrived quickly. Tried them out with NO balancing on them just out of curiosity, and they where pretty smooth. Offroad traction on trails has been great and these have taken the mildly modded Samurai to yet another level of improved capability. Previous tires were 10+ year old BFG AT with only 30% or so tread left and to be fair, I got them 2nd hand and didn't get to experience them new. So, probably any half way decent tire would have been noticeably better than old dried out tires, not matter how good they may have been when new. That being said, the Samurai nearly doubled it's abilities with it's 3" lift and move up to 31's... then adding a rear locker and proper diff gearing netted almost as big a gain again. Finally, adding these tires was not quite as big a jump as the other mods... but, again, a VERY noticeable gain in offroad traction and climbing ability. Long, 100% grade climbs that used to take effort and both hands and were a bit of a challenge, suddenly became casual, one hand on the wheel affairs. No chance to try them in in rain or snow yet.... but trail and rocky stuff has been great. Watch the "cooper puncture test" video online. As for noise.... my 4x4 is NOT my daily driver... so "tire noise" is more like TIRE MUSIC to me. But they are not particularly loud. Yes, you can hear them and they are more noise than your street car.... but, by FAR are NOT that noisy for mud tires. Prices on these fluctuate FAR more than BFG KM2 (my other choice).... but the BFG's would NEVER drop as low priced as these have from time to time.... When they dropped to only about $25 more than the cheapest tires out there, it was a no brainer! VERY pleased with them! [O.|||||.O] ... show more

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. ... show more

The tires are excellent for rock crawling, playing in the mud and sand excellent traction on gravel roads deep snow and slush. So far I have driven 6,000 highway miles on them and they still have the nipples on the tires. You must rotate them every 6,000 miles. And make sure they're still balanced. Downside is even though the tires are factory syped slowing down on wet roads and ice is terrible but you expect those two things when you order mud tires that's not made for either of those things for stopping power. ... show more

    • So far, so good.
Size: 35X12.50R20LT 121Q
So far, I’ve had theses tires on my f150 for 1300 miles. They are a little louder than I was hoping for, but I wasn’t surprised due to their aggressive design. They are a little louder than the Ridge Grapplers. They are similar to the nitto m/t on the noise level. They are reasonably smooth. Most of my driving, so far, has been on the highway with some on gravel roads. The tires look good with their aggressive tread design. The tires seem to handle as well as my ridge grapplers. I have reasonably high expectations for the mileage since that has been my history with Cooper tires in the past, but only time will tell. I have 7000 miles on the tires now, and they are holding up well. They’ve performed well through the summer on these hot Texas and NM roads. They do pick up and sling rocks if driven down gravel roads. ... show more

Been running these for about 5,000 miles and they are holding up Great! Much quieter than expected, no sliding in the rain like the stock tires, balanced well and great value for these tires. They run smooth but the only difference I noticed was losing approx 1 mpg. But for the value and performance, I'll take it. ... show more
