Cooper recently unveiled three updates to their popular Discoverer AT3 line of tires for off road enthusiasts, the Discoverer AT3 4S, the Discoverer AT3 LT, and the Discoverer AT3 XLT.
Discoverer AT3 4S
The Cooper Discoverer AT3 4S comes in 37 sizes (from 15- to 20-inch rim diameters) to fit a variety of SUVs, CUVs, and light trucks.
Designed with Adaptive-Traction Technology™, the Cooper Discoverer AT3 4S is designed to grip the road surface whether it is rocky or smooth, and under clear skies or severe weather.
The Discoverer AT3 4S has a patented saw-tooth pattern to trap snow inside the grooves to offer superior snow-on-snow traction and stopping distance.
A deep, uniquely-shaped center groove improves the Discoverer AT3 4S’s resistance to hydroplaning, and the smaller gauge zigzag sipes provide better stability and control and a better biting edge for wet/dry traction, while also reducing stone retention and drilling.
The Cooper Discoverer AT3 4S comes with a 65,000 mile treadwear protection warranty.
Discoverer AT3 LT and XLT
The Cooper Discoverer AT3 LT and Discoverer AT3 XLT are made with Coopers trademarked Durable Tread Technology to handle heavy loads with minimal wear while withstanding the assault of a gravel and dirt terrain.
Even Wear Arc Technology on the Discoverer AT3 LT and XLT tactically poise pressure at the contact area to promote even treadwear and better handling.
The downside to many all-terrain tires is the excessive road noise that traveling on asphalt creates. The Cooper Discoverer AT3 LT and XLT’s “Whisper Groove™” technology creates a sound barrier to reduce road noise.
With increased hauling weight comes an increased chance of stone retention. Because of this, the Discoverer AT3 LT and XLT features stone ejector ledges to protect the tire from stones drilling into the body of the tire, offering a clean tread for better traction.
Both the Cooper Discoverer LT and XLT offer a 60,000 mile treadwear protection warranty.
