New Discoverer AT3 4S Is Available in 37 Sizes

June 21, 2018

The new Discoverer AT3 4S for SUVs and light duty pickup trucks from Cooper Tire & Rubber Co. is available in 37 sizes from 15- to 20-inch rim diameters.

The Discoverer AT3 4S features Cooper's Adaptive-Traction Technology for gripping the driving surface, whether rocky or smooth, in hot or cold weather conditions.

A silica-based tread compound and Cooper’s Sure-Grip five-rib, all-terrain pattern provides off-road driving capability and excellent wet and dry traction. Cooper says zigzag sipes improve vehicle stability while reducing stone retention, and uniquely shaped deep center grooves reduce hydroplaning.

Severe weather rated, the Discoverer AT3 4S has a patented saw tooth technology designed to trap snow in the tread to provide superior stopping distance on snowy surfaces.
