Michelin 37968 X Tweel Turf 22x11N12 Airless Rear Tire – Spartan RZ, RZ PRO & RZ HD – Single

SOLD INDIVIDUALLY: Includes ONE Michelin Tweel tire/wheel unit. This is NOT a pair. Order a quantity of 2 if replacing both rear units.

The Michelin 37968 X Tweel Turf airless radial tire combines the tire and wheel into a single unit, replacing the conventional tire, wheel and valve assembly. Its airless design eliminates air-pressure maintenance, puncture-related flats and unseated beads.

Designed for the Spartan mower applications listed below, the X Tweel Turf maintains a consistent hub height to help support an even cut. Flexible poly-resin spokes carry the load and help absorb impacts, while providing lateral stability when mowing across slopes.

Features and Benefits

• Airless radial design: No inflation or air-pressure checks required.
• Integrated tire and wheel: Replaces the conventional tire, wheel and valve assembly.
• Consistent hub height: Helps maintain consistent mower deck height for an even cut.
• Multi-directional tread: Designed to provide traction and lateral stability while helping minimize turf damage.
• Heavy-gauge steel hub: Provides a durable mounting structure.
• Flexible poly-resin spokes: Support the load and help absorb bumps for operator comfort.
• Long-wearing design: Designed to deliver two to three times the wear life of a pneumatic tire at equal tread depth. Actual wear life varies with operating conditions and use.
