ARMOR-TEK3 CARCASS PROTECTION 
Cooper's proprietary and proven full 3-ply carcass construction in the tread and sidewall provides 50% more protection against impact damage than standard 2-ply tires. The third ply is oriented at an optimal angle to the first two plys to maximize carcass protection in extreme off-road conditions.

3-2 INNER TREAD RIBS 
The inner tread ribs of the Discoverer STT PRO are positioned in an alternating 3-2 pattern. This unique hybrid design provides a number of significant performance benefits like: reduced road noise, increased stability and handling, superior soft surface (trail) and mud traction, balanced wear, and reduced tendency for vehicle drift commonly experienced on fitments with aggressive off-road tires.

COUPLED SILICA TREAD COMPOUND 
The Discoverer STT PRO's tread compound is formulated with a chemically coupled silica and carbon black mixture that provides improved wet traction on-road and in slick situations encountered off-road. Cut and chip resistance in more harsh, rocky and gravel terrain is also improved.

FLEX GROOVE 
The "flex groove" is a small, circumferential groove in the buttress region that generates a designed flex point in the tire. This ability to flex in a predetermined location provides a smoother ride by helping to dampen the impact generated by inconsistencies in pavement, potholes and gravel. In tough off-road situations where tires are sometimes aired down, this groove allows the tread and side biter to better conform and work together when traversing irregular, tough obstacles.

ALTERNATING MUD SCOOP & ASYMMETRICAL SCALLOP 
The asymmetrical scallops on alternating lugs direct mud into the mud scoops to allow the Discoverer STT PRO to pull through muddy terrains with ease. These “scoops” act as shovels to consistently dig in as the tire rotates. Scoop by scoop the Discoverer STT PRO digs in and will confidently pull your vehicle through the toughest situations.
