Designed as original equipment for select Polaris Ranger models, the MU511/MU521 are ready to work. Featuring a generous contact patch and a robust, 6 ply-rated carcass, the MU511 front and the even wider MU521 rear ensure that you can haul heavy loads with ease. With a tread pattern similar to the Ceros, the MU511/MU521 also offers excellent traction and tread wear. Tall blocks and large void areas clear mud easily, so rainy, muddy weather is no problem for the MU511/MU521.
