Cooper Discoverer ST Maxx


When you need all-terrain tires that balance aggressive off-road traction with dependable on-road driving comfort, consider the Cooper Discoverer S/T Maxx for your light truck or SUV.

Cooper Discoverer ST Maxx Features

From one of the biggest names in off-road tire performance comes an all-terrain tire for the ages: the Cooper Discoverer S/T Maxx. Designed to work as hard as they play, Cooper ST Maxx tires have an aggressive tread design backed up by solid overall construction.

To make sure nothing puts a halt to your off-road journey or your workday, Cooper built the ST Maxx with its proprietary Armor-Tek3 technology, which resists punctures, tears and other damage in tough driving environments.

Cooper's 3-ply Armor-Tek3 technology helps reduce vulnerabilities in the tire's carcass, strengthening the tire and reducing the likelihood of serious damage.

But what does that actually do for you?

In a nutshell, when you outfit your light truck or SUV with Cooper ST Maxx tires, you can take point on some of the roughest trails out there without worrying if your tires will hold you back.

But the S/T Maxx is engineered for more than just rugged durability; it also delivers stellar off-road traction thanks to its aggressive, high-void tread pattern, while the dense network of sipes in its tread block work together to add traction and stability in wet road conditions.

Other performance features of the Discoverer S/T Maxx include:

    - A hybrid 4-5 tread block pattern that delivers off-road traction while reducing highway road noise and resisting uneven treadwear.

    - Added durability is provided by stone ejector ribs, which resist cutting and chipping caused by stone retention.

    - Pinned tread blocks allow for studding for extreme winter traction.

    - With its all-terrain traction and all-season capabilities, this tire is M+S rated, meaning that it exceeds the RMA's guidelines for a mud and snow tire.

    - Non-parallel groove walls provide increased resistance to stone drilling.

Cooper Discoverer S/T Maxx Treadwear and Warranty

Thanks to how Cooper engineered the S/T Maxx's 4-5 hybrid tread pattern and its silica-enhanced tread compound, the ST Maxx resists uneven treadwear. This means you get long-lasting, aggressive all-terrain performance.

However, if you want protection as robust as your new Cooper Discoverer ST all-terrain tires, consider investing in our exclusive Certificates.

Down to 3/32” of wear, our Certificates provide protection for your tires from the driveway to the worksite. And if your tires are ever damaged beyond repair, we'll provide you with a brand new replacement tire.

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

Whether you're commuting to a job site, going for a road trip, or leaving the paved road behind entirely, outfit your 4x4 or light truck with the Cooper Discoverer S/T Maxx. From there, you can take on whatever comes your way.

    These are the few tires that fit the odd size of my vehicle, I think they are excellent. It's also a pleasure to deal with my local DTC store on Milton Road in Flagstaff where the service is outstanding.

      I have to drive up a very steep levy, no tire slip at all. Probably 95% of people wouldn't think of driving up this levy in a truck. No issues at all

          My first set went 100k on the Toyota 4x4, low road noise for m/t, great off-road too….. I bought another set for the next 100k
