Roadian Mtx Mud Terrain. The Roadian MTX includes an aggressive design that is extremely versatile for on- and off-road driving. Each tire boasts a dual sidewall design that allows you to customize the look of the tire on your vehicle. The Roadian MTX also includes a standard 3-Ply design and F-Load weight rating that makes it extremely capable for heavy hauling. With such rugged traits you wouldn’t expect the Roadian MTX to be as quiet as it is on the highway, but thanks to its patented tread block design the road noise has been minimized. *By request/order.
