Cushothane® XL-AC™ polyurethane mold-on, press-fit and press-on tires run with the highest dynamic load capacity at the highest speeds.  Paired with low rolling resistance to extend battery life, Cushothane® XL-AC™ comes standard with SuperSmooth™ tread making it easier to roll and therefore draining less battery power and capturing more of the indoor AC-motor performance. They are also backed by the industry's only No Bond Separation Guarantee*.

Energy Efficient Polyurethane Compound:

The Cushothane® XL-AC™ is an energy efficient compound that reduces energy lost from tire deflection in the grip generating (contact patch) area. The lower energy loss creates less heat or cooler running tire that will reduce the chance of meltdown and bond failure and extend usage life. In addition, the tire is also easier to roll and thus drains less battery power – capturing more of the AC-motor performance.

Assembly Options:


Cushothane® XL-AC™ compound is molded directly to the mountable hub, providing the quickest and easiest way to install. Hub cannot be reused once the tire wears out.


Cushothane® XL-AC™ is molded to a press-on rim, which is then factory pressed onto a hub and sold as a single piece. This option has the benefit of quick and easy installation and allows for the hub to be reused when the tire wears out.

Tire Profile and Tread Style Options:

Smooth Crown (SC)

Pros - Best maneuverability and easiest steering

Cons - Lower stability and carrying capacity

Tapered Side Wall (TSW)

Pros - Best carrying capacity, with excellent stability, manuverability, and steering ease

Cons - No known limitations

Straight Side Wall (SSW)

Pros - Highest traction & stability from more ground contact. Typically used in Ultra-Large OD tires.

Cons - Reduced maneuverability and load capacity

Smooth Flat (SF)

Pros - Reinforcement band protects against undercutting caused from uneven loading or overloading

Cons - Slightly lower traction and stability

Tapered Side Wall (TSW)

Pros - Best carrying capacity, with excellent stability, manuverability, and steering ease

Cons - No known limitations

Center Groove (CG)

Allows for heat dissapation, reducing risk of meltdown in long runs applications. 

Also available in double center-groove (2CG) & triple center-groove (3CG)

X-Groove (XG)

Reduces hydroplaning in standing water and improves traction on wet floors.

Also available in double X-Groove (2XG)

X-Groove with Center Groove (XG With CG)

Reduces hydroplaning, side slippage, and improves traction on wet floors.

Suitable for medium to high standing water.

Diagonal Groove (DG)

Highest water dissapation, the most effective for wet floor conditions.

Suitable for high standing water. Provides smoother ride than X-Groove.


Ultra-fine diagonal cuts in the tread surface - best option for damp or icy floor conditions. 

Can be combined with other grooving options.

DISCLAIMER: All "Tread Styles" that involve the cutting or the removal of surface material will weaken the tire and increase the likelihood of "chunking". Superior Tire & Rubber Corp. recommends avoiding the use of these types of tread styles unless to solve a specific problem in your application.
