The Discoverer STT Pro is Cooper’s most advanced 4X4 extreme tyre to date. The Discoverer STT Pro provides exceptional traction and performance in some of the harshest terrains on earth. The distinctive tread design and compound provide remarkable on-the-road performance without sacrificing off-road traction. Push the Discoverer STT Pro to the limits and you’ll discover what your vehicle is truly capable of. Discoverer STT Pro “ARMOR-TEK ” CARCASS CONSTRUCTION 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 tyres. 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 tyres. LARGE DEPTH SIDE BITERS The Discoverer STT Pro features large, specially-designed cleats of rubber (side biters) on the shoulder area of the sidewall, to enhance traction and grip in muddy or soft terrains and in rock crawling situations where maximum grip is essential. The orientation and design of these cleats promotes traction on inclines, reducing the chances of tyre side-slip. FLEX GROOVE The “flex groove” is a small, circumferential groove in the buttress region that generates a designed flex point in the tyre. 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 tyres 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 AND 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 tyre rotates. Scoop by scoop the Discoverer STT Pro digs in and will confidently pull your vehicle through the toughest situations. MUD-FLEX DESIGN The mud-flex design is where the outside shoulder and intermediate tread ribs are strategically coupled together along their face. This connection creates a continuous cleating feature that assists the Discoverer STT Pro in digging through muddy terrain. The back side of this face is ramped to allow the tread blocks to work independently which provides better stability and tread conformity in less aggressive situations. ® www.coopertires.co.za

The Discoverer S/T Maxx features Cooper’s provenand reliable 3-ply “Armor-Tek 3” carcass constructioncombined with a new, proprietary cut and chip resistanttread compound. With that combination along with its modern hybrid 4-5 rib tread design and unique tread features, the S/T Maxx is a commercial grade traction tyre that will perform in the toughest terrains while retaining remarkable on-road traction, stability and relatively low noise characteristics.
Discoverer S/T Maxx
“ARMOR-TEK 3 ” CARCASS CONSTRUCTIONCooper's proven, class-leading 3-ply Armor-Tekconstruction contributes to the durability of the S/T Maxx byadding strength to the sidewall and tread area. A uniqueangled ply construction absorbs and helps dissipate tyreimpact forces that can damage a tyre in harsh off-roadconditions.
BLENDED NATURAL RUBBER AND SILICA-BASEDTREAD COMPOUNDThe tread compound is formulated with a unique blend ofnatural rubber and silica that provides exceptional wettraction and confident handling on the highway, while alsodelivering excellent cut and chip resistance on unpaved,rocky and gravel terrain.
STONE EJECTOR RIBSStrategically-placed ribs within the lateral grooves of thetread design help to discharge stones and resist stonedrilling.
ENHANCED BUTTRESS DESIGNThe optimised design of the buttress area providesadditional off-road traction, abrasion and punctureresistance. Its rugged design minimises the potential fordamage due to scrapes and abrasion when used in difficultterrain.
HYBRID 4-5-RIB TREAD PATTERNThe alternating 4-5-rib tread pattern gives the S/T Maxx abold look, while providing enhanced on- and off-roadperformance. The pattern geometry and internal sipingprovide an optimised blend of all-season and off-roadtraction performance. The 4-5-rib tread element design ofthe S/T Maxx randomises tread block impacts with the roadsurface resulting in relatively low noise characteristics.
MICRO-GAUGE SIPING WITH ROUNDED CORNERSThe micro-gauge sipes in the tread provide increased treadblock rigidity and vehicle stability while reducing the potentialfor stone retention and stone drilling into the tread elements.The rounded corners reduce stress concentrations toenhance crack and tear resistance of the tread blocks.

MODERN AGGRESSIVE 5-RIB ALL-TERRAIN DESIGNThe aggressive all-terrain design is engineered to provideoutstanding performance in both on-road and off-roaddriving applications. The A/T tread pattern exploits acombination of features specifically suited to provide solidall-terrain performance, superior all-season traction,excellent stability, confident handling and reliable treadwear.
SILICA-BASED TREAD COMPOUNDThe tread compound is formulated with a chemically-coupled silica and carbon black mixture that providesexcellent wet traction and handling on the highway, whilealso improving cut and chip resistance in more harsh rockyand gravel terrain. The silica-enriched tread compound haslower rolling resistance than traditional full carbon blacktread compounds.
DUAL DRAFT TREAD ELEMENT WALLSThe dual draft angles on the tread element walls aid inreducing stone retention, stone drilling and assist in cut andchip resistance.
LATERAL GROOVE PROTECTORSSerrated steps in the lateral grooves of the intermediatetread rib reduces the chance of stone retention and stonedrilling.
MICRO GAUGE ZIG-ZAG SIPINGThe smaller gauge sipes in the tread elements provideincreased vehicle stability and control, while reducing thepotential for stone retention and stone drilling. The zig-zagshape creates more biting edges which allow for better softsurface and wet traction.
COUPLED TREAD ELEMENTSThe centre and intermediate tread elements are uniquelydesigned in pairs affording excellent stability and confidenthandling.
BROKEN CENTRE RIBThe broken centre rib improves soft surface traction without sacrificing handling.
