Frequently Asked Questions
Q: What is Cushothane EZ 85A material and how does it differ from standard polyurethane?
A: Cushothane EZ 85A is a proprietary soft polyurethane formulation engineered to resist cracking and maintain elasticity in cold environments and high-cycle applications. The 85A Shore hardness rating means it is softer and more flexible than standard poly (typically 90-95A), providing better shock absorption on irregular floors. EZ stands for Easy Maintenance because it resists oil absorption better than standard poly. Cushothane EZ lasts longer (4 to 5 years versus 2 to 3 for standard poly) but costs more upfront. Use EZ in freezers, cold-storage operations, or where floor abuse is high.
Q: Can I install the SU 10X475X65-SF-EZ tire on a wheel that previously had a rubber tire?
A: Yes. The SF-EZ is a 10x4.75 inch tire on a 6.5 inch rim width, same as most rubber equivalents. Check the wheel hub bore diameter to confirm it accepts the 6.5 inch rim. If your previous tire was also 6.5 width, installation is direct swap. Use a 20-ton press to remove the old tire and install the new one. Do not attempt manual installation; poly tires bond tightly to rims and require equipment to mount safely. After installation, allow the tire 24 hours before operating so the rim bond sets properly.
Q: How do I know if my SF-EZ tire is degrading due to cold storage exposure?
A: In cold-storage settings (0 degrees Fahrenheit and below), monitor for hairline cracks forming in the sidewall or tread area, especially near the rim where stress concentrates. Press the tire with your hand; if it does not spring back quickly or feels permanently dented, the polymer chains are breaking down. Discoloration or chalky residue on the surface also indicates degradation. Cushothane EZ resists this better than standard poly, but nothing stops it completely below zero. Plan for tire replacement every 2 to 3 years in freezer duty instead of the standard 4 to 5 years.
Q: What are the torque and pressure specifications for mounting the SF-EZ tire?
A: Press-on tires like the SF-EZ do not require inflation or inflation pressure; they are solid foam-filled or bonded directly to the rim with no air chamber. If your specific wheel design uses a valve stem for pressure monitoring only, pressurize to 5 to 10 PSI (consult the lift truck manual). When pressing the tire onto the rim using a 20-ton shop press, apply steady, even pressure and stop when the tire seat fully contacts the hub flange (approximately 8 to 12 tons of force depending on rim condition). Uneven pressing can crack the tire or bend the rim.
Q: Is the SF-EZ tire more expensive than standard poly, and is it worth the cost?
A: Yes, Cushothane EZ 85A tires cost 20 to 30 percent more than standard polyurethane tires. The investment pays for itself if you operate in cold storage (where EZ lasts 4 to 5 years versus 2 to 3 years for standard poly) or in high-cycle environments with frequent turning and heavy loads. In mild warehouse conditions, standard poly is more economical. Calculate your annual cost per operating hour: if EZ adds 18 extra months of life in your conditions, the per-hour cost is lower. Cold-storage users should choose EZ; general warehouse users can use standard poly.
