Maxxis MU521 Rear UTV Tire

The MU521 is the rear member of Maxxis’s utility tire pairing for demanding work and trail conditions.

Features and intended terrain

• A directional pattern and tall tread blocks help release mud and debris.
• Extended shoulders and rim protection support use on rough worksites.

Intended terrain: Hardpack. Riding use: Utility.

Specifications by size

Nominal dimensions are tire height × tire width × rim diameter, in inches. Tire width is not approved wheel width. A dash means the specification has not been confirmed.

Additional verified specifications

Listed pressure values belong to the manufacturer’s specification or load table. They are not a universal riding-pressure recommendation.

Fitment checks before ordering

Confirm tire height, width, rim diameter, approved wheel width, load capacity and axle position against the vehicle and wheel manufacturer’s requirements. Check clearance at full steering lock and throughout suspension travel. Rim diameter alone does not establish vehicle fitment. Follow rotation markings and professional mounting instructions.

What is included

One tire in the selected size and version. Wheel, mounting, hardware and additional tires are not included.

Frequently asked questions

Is the price for a set?

No. Each selected SKU includes one tire. Order the required quantity for your vehicle.

Will this fit any UTV with the same rim diameter?

No. Match all dimensions, load requirements, wheel-width compatibility and clearances before ordering.

Which Maxxis MU521 Rear version should I choose?

Start with the required size, then compare the listed compound, position and ply rating. Blank specifications need confirmation rather than an assumption from another size.
