Cooper Discoverer STT Pro Tire Review & Rating

The Cooper Discoverer STT Pro is the company’s newest addition to its off-road performance lineup. Built as a replacement to the original STT, Cooper has designed this new tire to tackle the toughest of off-road terrain, yet remain well-mannered enough for regular on-road driving needs.

An advanced silica and carbon black tread compound combines with 3-Ply Armor-Tek3 protection that helps prevent damage from rocks, trees and other debris. It results in 50% more protection over a standard 2-ply tire. Unique shoulder cleats, or sidebiters as they are also called, along the outer sidewalls provide additional grip and traction on all types of terrain.

While this tire is built to handle rock, sand, dirt, grass, fallen trees and other debris with relative ease, one area where Cooper’s engineers spent considerable time in development is mud performance, and it shows. They have added mud release dimples to the outer lugs which help the tire rid itself of mud buildup, while unique scoops on the outer lug face increase traction in the deeper muck.

Naturally, taking a look at this aggressive mud-terrain tire will have you thinking it has to be loud on pavement. The truth is, the STT Pro is not all that loud considering its profile. A 3-2 rib pattern is designed to cancel out excessive road noise through its alternating sizes, angles and number of ribs around the tread. Flex Grooves also help in reducing the jarring effects of potholes and bumps in the pavement while delivering a smoother and more stable ride quality.

Sizes run from 15-22 inches and are available with C, D or E load ranges.

Pros

  • Aggressive and tough as nail tread design
  • Off-road performance, especially on rock
  • Handles well on wet/snow covered road surfaces
  • Treadlife

Cons

  • High quality off-road tires are not cheap

Overall Thoughts

If you liked the performance from the original STT from Cooper, you’re going to really enjoy driving on the new STT Pro. It’s hard to find fault with any single area on this tire. Sure, you could say it’s not a hard-core mud tire, but it doesn’t pretend to be. That said, it compares favorably with the likes of the BFGoodrich KM2, Goodyear MTR Kevlar or any other top model.

One thing to keep in mind is that this is a heavy tire amongst others in this class due in part to how it is constructed. That said, we’ve heard a number of drivers mention how easy it is to get this tire balanced.

Overall, if you’re looking for a tough MT tire that is up to the task for anything off-road, yet you still need to be able to drive it down the highway without having to blast the radio or visit the chiropractor later, the Cooper STT Pro is one of the best tires in this category.
