The rear tire (equivalent to the front tire MU-511), the Maxxis MU-521 is a tire for side-by-side type quads with an aggressive profile. It is notably standard equipment on Polaris Rangers. The tread pattern is similar to that of the Maxxis Ceros. The wide central and lateral lugs provide optimized traction on all types of terrain, ensuring biting and self-cleaning. The slight V-tilt of the lugs towards the center of the tread ensures perfect stability on muddy terrains, skidding is not allowed. The 6-ply carcass is very resistant to punctures and wear. The load capacity is particularly high.
