5-Rib All-Terrain Design:
The modern all-terrain design is engineered to provide outstanding performance in both on-road and off-road driving applications. The A/T3 tread pattern exploits a combination of features specifically suited to provide solid all-terrain performance, superior all-season traction, excellent stability, confident handling and reliable tread wear.
Broken Centre Rib:
The broken centre rib improves soft surface traction without sacrificing handling.
Dual Draft Tread Element Walls:
The dual draft angles on the tread element walls aid in reducing stone retention, stone drilling and assist in cut and chip resistance.
Lateral Groove Protectors:
Serrated steps in the lateral grooves of the intermediate tread rib reduce the chance of stone retention and stone drilling.
Coupled Tread Elements:
The centre and intermediate tread elements are uniquely designed in pairs affording excellent stability and confident handling.
Armor-tek³ Carcass Construction:
Cooper’s proven, class-leading 3-ply Armor-Tek3 construction contributes to the durability of the S/T Maxx by adding strength to the sidewall and tread area. A unique angled ply construction absorbs and helps dissipate tyre impact forces that can damage a tyre in harsh off-road conditions.
Hybrid 4-5 Rib Tread Pattern:
The alternating 4-5 rib tread pattern gives a bold look, while providing enhanced on- and off-road performance.
Asymmetric Dual Draft Tread Element Walls:
The asymmetric and dual draft angles along the tread element walls aid in reducing stone retention and stone drilling and increases their resistance to cutting and chipping when used in gravel or off-road applications.
Stone Ejector Ribs:
Strategically placed ribs within the lateral grooves of the tread design help to discharge stones and resist stone drilling.
Rut Guard Rib:
A continuous rut guard is strategically placed in the upper sidewall area of the tyre, to deflect objects and provide for increased abrasion resistance in tough, uneven terrain.
M+S Rated and Studdable
Large Tread Elements:
The large surface-area tread elements provide positive grip and even
wear for excellent on and off-road performance.
The Discoverer STT PRO™ is the most extreme all-season, off-road tire Cooper® offers to date, providing remarkable off-road performance without sacrificing on-road traction.
