Frequently Asked Questions
Q: What does Cushothane EZ 85A mean on the SU 10.5 X 5 X 6.5-SC-EZ wheel?
A: Cushothane EZ 85A is a proprietary polyurethane formulation rated at 85A durometer hardness. EZ refers to a softer, more compliant compound designed for lighter duty and improved shock absorption. This wheel is ideal for operations requiring a gentler ride and reduced vibration transmission. Do not confuse EZ with XL formulations, which are harder and designed for higher load applications.
Q: Is the SU 10.5 X 5 X 6.5-SC-EZ compatible with my existing 10.5 inch wheel hubs?
A: Yes, the 10.5 inch diameter is standard. Verify your hub uses 6.5 inch center spacing (not 8 inch). The 5.000 inch width is wider than standard 4 inch or 4.5 inch wheels. Before installation, confirm your lift truck frame has sufficient clearance and that all four wheels are the same width and hardness to prevent handling imbalances and uneven wear.
Q: What is the load capacity difference between SU 10.5 X 5 X 6.5-SC-EZ and harder polyurethane wheels?
A: The 85A durometer EZ compound has lower load capacity than 97A XL wheels. Use EZ wheels for lift trucks rated under 3500 pounds per wheel. XL wheels support higher loads. Check your lift truck nameplate for maximum load rating and choose wheel hardness accordingly. Mixing wheel hardnesses on the same truck causes uneven load distribution and premature failure.
Q: How do I distinguish between the SU 10.5 X 5 X 6.5-SC-EZ and SC-XL wheels?
A: Both have smooth crown profiles but different durometer ratings. EZ 85A is softer and compresses more under load. XL 97A is harder and maintains shape better under heavy loads. Feel the sidewall; EZ wheels have more give when pressed with a finger. Check the part number carefully; EZ and XL are not interchangeable. Mixing them causes tracking problems and vibration.
Q: When should I replace the SU 10.5 X 5 X 6.5-SC-EZ wheel?
A: Replace when the polyurethane shows permanent indentation from hand pressure, visible cracks radiating from the center, or chunks missing from the tread or smooth crown. The softer EZ compound typically shows wear faster than XL. If the wheel feels squishy or loses its round shape, it has reached end of life. Do not wait for catastrophic failure; replace at first signs of degradation.
Q: What environmental factors degrade the SU 10.5 X 5 X 6.5-SC-EZ wheel faster?
A: The softer EZ compound is more sensitive to heat, UV exposure, and oils than XL. Store indoors away from direct sunlight. Avoid contact with petroleum products, acids, and harsh cleaners. High temperature environments accelerate hardening and cracking. Cold storage below 32 degrees F makes EZ compound temporarily brittle; allow warm-up before operation. These factors reduce EZ wheel lifespan significantly, sometimes to 6-12 months in harsh conditions.
