Features of Cooper AT3

While driving your vehicle off roads, the tire faces solid substances like rocks, sharp materials that shred the tire that decrease the tire’s lifetime. Cooper AT3 is designed with high shredding protection ability, which tramps through those hard substances and you get a perfect driving in off roads and rough surfaces.

Tire Design

Cooper AT3 provides an eye-catching design along with the grooves in it. With these nicely and technically designed grips, this tire can respond to sudden braking, acceleration of the vehicle, quick steering and turning both in smooth and rough surfaces. For this reason, people usually choose the Cooper AT3 tire for their vehicle wheel.

Snow Groove Technology

Developed by Snow Groove Technology, the Cooper AT3 tire contains severe grips. In icy roads, the road surface does not include grooves, as a result of which the friction between the vehicle tire and the road surface is also less there. This will increase the possibility of an accident during the acceleration of the vehicle as the driver would not be able to stop the vehicle. For this reason, the Cooper AT3 tire will be helpful on those roads.

Treadwear Protection

Usually, the treadwear of a tire means how long a tire can last. On average, from 50000 miles to 70000 miles is considered as a standard tread wear rate. The Cooper AT3 tire is capable of providing 65000 miles of treadwear protection to the vehicle.
