As a tire which focus is on all-terrain capability, it’s a bit different than pure mud or off-roading tires. The tread pattern is not as deep or as harsh as pure mudding tires, which should work to help reduce the noise they generate on highways. Striking a balance between pure off-road capability and everyday driving, Encounter AT tires can offer good value. Molded into a symmetrical tread pattern with deep tread grooves. The tire should resist wear and provide a more comfortable ride in part because of this tread design. When a tire surface wears evenly, it can reduce the bumps or warping which may cause an early end to useful life. 

Four large grooves run the circumference of the tire. These deep channels between large tread blocks create good drainage for water to be cleared from the bottom of the tire. Water is also forced out the sides through lateral grooving, while tire rubber bites down on hard pavement. When rubber contact is maintained on hard surfaces, the tire can keep grip and resist some of the affects of hydroplaning. Three tread strips form the inner blocking, creating a wide, continuous footprint on the road. These patter designs should help reduce the noise generated by the tires when on paved surfaces and can provide extra grip on loose surfaces like mud, sand or gravel. 

Built into the large tread blocks which line either shoulder are specially designed 3D sipes. These small, zig zag shaped grooves give the tread extra flexibility. They act as extra grab points for treads, pinching down onto loose surfaces like snow, mud or sand. This can result in better traction on a variety of softer or off-road surfaces. The tread of Encounter AT tires has been tested and meets the requirements for the three peak mountain snow flake symbol. While not a true winter tire, it should provide some good light snow and cold weather traction. Shaped treads are staggered along the tire shoulder. These can help keep stones and other objects from getting stuck between tread blocks. 

Internal construction has features nylon wrapped steel belts, reinforcing the structure of the tire. When the terrain is less than ideal, strengthened tires should maintain their shape as the weight of the vehicle is transferred. Keeping rigid sidewalls can also improve general ride quality, particularly when under the heavy load of towing or payloads.
