Features of Cooper AT3
While driving your vehicle off roads, the tire faces solid substances like rocks and sharp materials that shred the tire that decrease the tire’s lifetime. Cooper AT3 is designed with high shredding protection ability, tramps through those hard substances, and you get perfect driving 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 on smooth and rough surfaces. For this reason, people usually choose the Cooper AT3 tire for their vehicle wheels.

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 vehicle’s acceleration, 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, a tire’s treadwear 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.

Features of ST Maxx Tire

Dual Draft Groove Walls
The ST Maxx vehicle tire is capable of better stone retention and cutting. The dual groove walls are used in that tire to provide more performance to the vehicle. The grooves are nonparallel, which significantly helps in perfect gripping with the road surface, resulting in the tire’s better chipping ability than the conventional vehicle tires.

Better Durability
The durability of a thing depends upon how long that thing can last and gives better performance. This factor is one of the most crucial factors for choosing the better tire for your vehicle because changing the tire eventually costs more money than expected. For this reason, to save you monetary loss, the Cooper tire brand specially designed the ST Maxx version, which has more capability of giving better durability.

Tread Block Pattern
The ST Maxx vehicle tire has a hybrid 4-5 tread block pattern with an unparalleled groove that helps drive on rough surfaces. On the off-roads, the stones cause most of the damage to the tire by stone retention. The ST Maxx resists the cutting and chipping caused by the stone.
