Armor-Tek3 Carcass Construction

Cooper's proven, class-leading 3-ply “Armor-Tek” 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 tire impact forces that can damage a tire in harsh off-road conditions.

Blended Natural Rubber and Silica Based

The tread compound is formulated with a unique blend of natural rubber and silica that provides exceptional wet traction and confident handling on the highway, while also delivering excellent cut and chip resistance on unpaved, rocky and gravel terrain.

Stone Ejector Ribs

Strategically placed ribs within the lateral grooves of the tread design help to discharge stones and resist stone drilling.

Enhanced Buttress Design

The optimized design of the buttress area provides additional off-road traction, abrasion and puncture resistance. Its rugged design minimizes the potential for damage due to scrapes and abrasion when used in difficult terrain.
