Cooper Discoverer STT Pro


Are you searching for a great way to amp up the excitement in your off-road antics? Consider outfitting your light truck or SUV with a set of rugged Cooper Discoverer STT Pro mud terrain tires.

Cooper Discoverer STT Pro Features

Designed to enhance the performance of any off-roading vehicle, the Cooper STT Pro is a Mud and Snow (M+S) rated tire with the aggressive performance you need to take on the toughest trails. If you're the type of driver looking for any opportunity to venture off the beaten path, the Discoverer STT Pro is a maximum traction tire that will help you take on whatever your adventure throws at you.

Cooper knows few things can put a stop to an off-road adventure like tire damage. That's why Cooper engineered STT Pro tires for unprecedented toughness using their proprietary Armor-Tek3 technology.

So what is Armor-Tek 3 technology?

Unlike standard 3-ply constructed tires, where the plies are built running at the same angle, the Cooper Discoverer STT Pro is engineered with a third ply running at a slightly different angle. This simple change reduces the number of weak points in the tire's sidewall.

What does that mean for you? More tear and puncture resistance so you can go off-road with absolute confidence.

Other performance features of the Cooper STT Pro include:

  • An aggressive high void tread pattern that works to clean mud and debris from its contact patch for maximum traction.
  • Mud release dimples that assist in clearing mud and sand from the tread pattern for increased traction.
  • Durability and resistance to stone-drilling via anti-stone retention ribs.
  • For grip in soft terrain like mud and sand, they feature alternating shoulder lugs.
  • A center tread area that utilizes a 3-2 block pattern, increasing stability for reliable on-road driving manners.

Cooper Discoverer STT Pro Treadwear and Warranty

When you're planning an off-road excursion, you want to be confident your tires can take on whatever you throw at them. And if you outfit or upfit your rig with these Discoverer STT Pro tires, you're basically putting some of the toughest rubber out there on the road (or trail).

But if you're looking for confidence that goes beyond any tire's capability, you can always opt to cover your STT Pro tires with Discount Tire's exclusive Certificates.

Our Certificates are the most robust protection available for your tires, and they'll cover your set of Discoverer STT Pros from the parking lot to the trails and back, all the way down to 3/32”. And while these Discoverers are durable enough to withstand some of the harshest terrain and conditions out there, if they do sustain any non-repairable damage we'll provide you with a brand new replacement.

(You can add our Certificate coverage in the cart of your order.)

When you get that itch to go off-roading, be sure your 4x4 is kitted out with an off-road tire that delivers unyielding performance no matter the challenge—a tire like the Cooper Discoverer STT Pro.

    Hands down the best mud tire I’ve ever put on one of my trucks. I was iffy and decided to give em a shot, and I’m glad I did. The rubber is soft enough for a comfortable ride, and firm enough for some serious off road traction, and doesn’t chip or cut in rocky terrain. This will be my go to tire from here on out, pricey but worth every penny so far!!

      I love these tires and they are on all four of my trucks just so you can see how much I do love them. I also tell everybody about Discount Tire and you guys don’t even pay me for it. Lol
