Cooper Discoverer AT3 4S Features

Think of the Discoverer AT3 4S as a bodyguard in a business suit. It's durable and ready for the rough stuff, but it's also maybe even a little unassuming compared to the tread and sidewall designs of other aggressive all-terrain tires out there.

In fact, the truth of this Cooper Discoverer is that it's ready for anything. Loaded with Cooper's cutting-edge tire development technologies, it's a tire that's built to last and lay down comfortable performance on any type of on or off-road condition.

Specific performance features of the Cooper Discoverer AT3 4S include:

• Micro-Gauge zigzag sipes increase stability and control for wet and dry traction while reducing the possibility of rocks getting stuck in its tread.
• Its Secure-Gripall-terrain tread design packs in five ribs for increased flexibility and support when off-roading.
• Hydroplaning resistant Aqua Vac Channelsin its deep center grooves make the AT3 4S easier to control on wet roadways.
• Snow Groove Technology is Cooper's difference-maker in winter weather, which traps and packs snow into the AT3 4S' tread to provide sticky traction when you need it most.

Compared to prior Cooper Discoverer and Cooper Discoverer AT3 tires, it even reduces braking distances on snow by an average of 20 feet. When it comes to performance, comfort and safety, the AT3 4S could be the perfect tire for your truck or SUV.

Cooper Discoverer AT3 4S Treadwear and Warranty
