Cooper STT

ARMOR-TEK3 CARCASS CONSTRUCTION

Coopers STT is now 33% stronger in the sidewalls and 2.5 times more resistant to tearing. Its the heavy duty carcass that makes the new STT so special. In a normal 4WD tyre there are rubber gaps between the sidewall cords. The rubber gaps are the weakest point of the tyre. A nail, a stake or sharp outback grass can push against the sidewall cord, deflect off and penetrate through the weakest point, (the rubber) and you get a flat. What Cooper has done is reduce the rubber gaps by taking its 2 ply STT and added a third ply on an angle (an 8 degree angle). Its called Armor-Tek3 technology and its unique to Cooper.

CUT & CHIP RESISTANT

The new STT is even more damage resistant with a specially developed tread compound to help reduce the cutting, tearing and chunking commonly found with extended outback use.

SUPER TRACTION TREAD

A super traction tread employs a combination of features including deep sidewall lugs, notched and scalloped shoulder lugs, and a unique centre traction zone to create a bold, aggressive tyre. Sipes (tiny cuts in the tread blocks that squeeze out water from under the tyre) provide excellent wet bitumen grip for an aggressive traction tyre.
