Maxxis - maxTM00140000 - MU521 27x11.00R14 6PR TL Tire

Engineered for heavy-duty utility and demanding trail conditions, the Maxxis MU511 (Front) and MU521 (Rear) tires deliver maximum load-carrying capability, stability, and off-road control. Originally equipped on select Polaris Ranger models, these tires combine a generous contact patch with a rugged 6-ply rated carcass built to handle heavy farm work and commercial hauling without flexing under pressure. Modeled after the proven Ceros directional tread pattern, the MU511/MU521 utilizes tall tread blocks and large void spacing to shed mud and debris quickly, ensuring consistent traction across dirt, gravel, rocks, and wet terrain.

• Integrated rim protection guards wheel flanges against impact damage from sharp rocks and hidden obstacles
• Extended shoulder lugs bite into sidewalls to help pull the vehicle out of deep ruts and loose soil
• Siped tread blocks enhance wet surface braking and improve cornering bite on off-camber trails
