CUSHOTHANE® ULTRA-ES™
- Heaviest load & highest duty cycle tire compoundIntroducing our newest polyurethane compound delivering higher strength, lower operating temperature and lower battery drainage, while maintaining 93A hardness and flexibility required for demanding tire applications.
- Extended service, longest lasting - Highest abrasion resistance, proven on DIN Abrasion test* and side-by-side field tests.
- Ultimate chunking resistance - Advanced polymer formation produces a more organized rigid nano-structure that provides higher cut & tear compared to traditional high performance MDI systems.
- Higher performance & quality consistency - Innovative “End-Terminated” crosslink agent allows for a highly controlled reaction process.

Got Questions?
We engineered the Cushothane® ULTRA-ES™ polyurethane mold-on and press-on tires for the most demanding electric fork trucks. Extended service significantly reduces replacement cycles, downtime and all costs associated. The Cushothane® ULTRA-ES™ tires perform at temperatures well below freezing and stand-up to high speeds, loads and duty.
Physical Properties:
It's All in the Chemistry
The extraordinary performance of Cushothane® ULTRA-ES™ comes from its well organized and evenly distributed polymer structure. Polyurethane compounds are made up of a distribution of polymer sizes and compositions. Compounds with more organized structures offer a balance of properties with better cut and tear, higher abrasion resistance and much lower energy loss.
Incredible Low Temperture Performance:
Cushothane® ULTRA-ES™ has a very low glass transition temperature and maintains flexibility & chunking resistance at very low freezing temperatures common to blast freezer applciations. European Ultra Premium compounds tend to get harder and brittle once temperatures drop to this level.

Assembly Options:
Mold-On
Cushothane® ULTRA-ES™ 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.
Press-Fit
Cushothane® ULTRA-ES™ 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.
Siped
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.
