DESCRIPTION

Cooper's STT is now 33% stronger in the sidewalls and 2.5 times more resistant to tearing. It's 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 outstanding 2 ply STT and added a third ply on an angle (as 8 degree angle).
