Product Description

When you drive a light truck and need to head off the beaten path from time to time, you need a tire that will withstand what the trails throw your way. The Cooper Discoverer STT is Cooper's premium off road tire for light truck, SUV, Jeep and off-road vehicle use. These tires are versatile and are made for a variety of applications. The Discoverer STT is perfect for your personal truck or SUV, but are made to withstand commercial use as well.

As with every Cooper tire, this tire is made with long-lasting materials and the best manufacturing processes. The Cooper Discoverer STT tire is also made with Cooper's patented ArmorTek3 construction process. Cooper makes each of these tires with two radial polyester body plies and one angled polyester body ply. This gives the tire three heavy-duty plies to protect from punctures and other damage. The tread also extends further down the sidewall to increase traction and grip in those off-road situations where you need a little extra hold.

Cooper tires consistently receive high safety ratings, and the Discoverer STT is no exception. This tire is great on pavement, off-road and in inclement weather. The Discoverer STT is made to get the best traction no matter the surface. No matter if you are on dry pavement, a slick, wet trail or a field full of mud, you can count on the Discoverer STT to take you where you need to go.

The Cooper Discoverer STT also performs well. This tire helps increase the performance of your vehicle without adding a lot of extra and unnecessary road noise. Many off-road tires are loud and can deter truck owners from wanting to go on road trips or spend many miles on the roads in their trucks. The Discoverer STT is quieter than the competition, so you get the performance without the headache. Best of all, you won't see a drastic reduction in fuel economy like you might from similar off-road tires from other brands.

When you choose a tire, you also want to find a tire that looks great and complements the look of your vehicle. The Cooper Discoverer STT gives your truck an aggressive stance that lets everyone know you mean business. The Cooper Discoverer STT is economically-priced, so you get a great tire without breaking the budget. This tire is offered in a wide variety of sizes to fit almost every vehicle. This is one of the most versatile off-road tires, and one of the most popular.

I have owned several different brands of Mud Terrain Tires and these have been absolutely my favorite so far. Customer Service @ Tire Crawler.Com was Top-Notch also.

Haven't had a chance to really test them out yet but the installer said they balanced nice for 35's with minimal weights. They look awesome! Pictures don't do them justice. Amazed at how fast they showed up! 4 day turnaround from ordering to arrival. When they say brand new they mean it too! My tires were made in September 2014! Thanks Tirecrawler!

I put over 70,000 miles on a set of these. Drove in over 17 different states, went from Pennsylvania, to Montana, Washington, Utah, Texas, back to Pennsylvania and all the states between. Rain, hail, snow, ice, mudd you name it, they will perform for you.

I had never shopped with tire crawler before and I didn't live in the same state so I was a little worried. I was impressed with the service and how easy they made it. When I got the tires they were in perfect condition and better then what I expected.

I've used Tire Crawler for (3) sets of tires now. I have ordered over the phone and on line. The tires show up at my front door usually in 2 or 3 days. I save over $100 per set of tires, and this AFTER shipping and having them mounted and balanced at a local tire shop. I've been buying Cooper tires because they have the tread pattern I'm after, and they work awesome in winter month snow and ice. I highly recommend coopers, and Tire Crawler! Ronny

These tires look great on my Titan! There is a little road noise but I really can't hear it over my dual exhaust. I really hope I can get a lot of mileage on these tires. But after 5000k, I absolutely love them and would buy them again.

I use these tires for my work truck in the oil fields of Utah. 200+ miles of dirt roads every day. I've never had a flat, get great traction in mud, snow, and sand. Average about 30,000 miles per set in very harsh conditions. I just ordered a set in 35x12.5 for my jeep. Can't wait!
