Description

The Cooper Discoverer STT Pro All-Season LT315/70R17 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.

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.

30,000 mile review
Size: LT305/60R18 121/118Q
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! ... show more

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
So far, so good.

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

This is my second set of these tires
Size: LT315/70R17 121/118Q
My first set of the Discovery STT Pro lasted approximately 42,000 miles and still had enough tread to go another year. I decided to swap out my old tires because they have been on my Jeep for almost 10 years and due to an alignment issue there was some cupping. The new tires are amazing. There is very little road noise and the Jeep handles very well. I think as these tires wear out the road noise will increase (I believe this has been typical of other tires I've had on my previous Jeep). Overall I am very happy with the previous tread life of these tires and impressed with their on-road performance. ... show more

Amazing tires
Size: LT265/70R17 121/118Q
I live in Alaska, they shipped here on prime delivery at 65 bucks cheaper per tire than in the shop. They will do a ton of crazy off roading this summer. Amazing tires. Track well in rain, haven't tried snow as I usually run a dedicated snow tire but will be great for the shoulder season.
