The MASSFX MO tire was built with one thing in mind, fun. Theyre best suited for sport quads due to their dynamic tread pattern that can grip the terrain in any direction. Theyre perfect for the hard turns and fast straightaways that a sport quad is built for. This tread pattern also offers exceptional acceleration and traction on all surfaces. The 4-Ply construction offers durability without sacrificing a comfortable ride. With these tires, you can be "Doing Fun Right" too.
