Pro Comp Radial Xterrain Tire is two tires in one. The aggressive directional tread provides superior traction compared to standard all terrain tires, yet is surprisingly quiet on the street. Its staggered directionally grooved tread pattern has full length lug sipes for superior traction that makes it superior in mud, snow, slush, loose dirt, rock and road. Its alternating open lug shoulder grip spurs aid in increased traction and self-cleaning. The Pro Comp Xterrain's extra thick side wall treatment helps resist scrapes and cuts, maximize a biting edge side wall for increased traction on rocks or in mud. Dual guard Polyester Body Plies consist of thick polyester construction combined with a blend of side wall rubber allowing for maximum puncture resistance with total flexibility when using lower air pressure.
