Frequently Asked Questions
Q: What is Cushothane EZ 85A and how does it compare to other poly tire materials?
A: Cushothane EZ 85A is a polyurethane compound rated at 85A durometer hardness, providing a balance of grip and resilience. EZ denotes an easy-pressing compound that requires lower press-on forces than harder materials like XL 97A. At 85A, this tire is softer and provides better traction and load distribution on smooth floors but wears faster than harder alternatives. Use EZ 85A on low-impact, smooth floor applications where traction is prioritized over tire lifespan.
Q: Is the SU 10x4x6.5-SC-EZ tire compatible with lift trucks that previously used rubber tires?
A: Yes, the SU 10x4x6.5-SC-EZ is a direct replacement for rubber tires with the same 10 inch diameter, 4 inch width, and 6.5 inch bore. Poly tires offer 30 to 50 percent longer service life than rubber and require less frequent replacement. Installation procedure is identical: use a press machine and verify bore size. No modifications to the truck are needed.
Q: How does the SU 10x4x6.5-SC-EZ crowned profile affect tire performance?
A: The crowned profile means the tire center is raised slightly higher than the edges, creating a convex shape. This crown improves directional stability and reduces wandering on straight runs. The crown also helps the truck corner more precisely by loading the outer tire edge first, improving steering control. Crowned tires generate slight lateral torque, so left and right tires must be matched pairs to ensure balanced truck handling.
Q: What is the proper press-on installation procedure for the SU 10x4x6.5-SC-EZ?
A: Use a hydraulic press with arbor dies matched to the 10 inch tire diameter. Apply steady pressure at 3 to 5 tons force, which is lower than rubber due to the softer EZ compound. Press the tire fully onto the hub until the bore seats completely. Check that the tire is centered and does not tilt. Allow 2 to 4 hours for the polyurethane to set before operating under full load. Do not operate until the tire compound has cured fully.
Q: What load and speed ratings apply to the SU 10x4x6.5-SC-EZ?
A: The SU 10x4x6.5-SC-EZ is rated for 1200 to 1800 pounds per wheel at 10 to 15 miles per hour continuous duty. The softer EZ compound allows slightly higher load capacity than rubber at the same size. Operating above 15 mph or exceeding wheel load rating causes heat buildup and tire deformation. For high-speed or high-load applications, consider the harder XL 97A alternative instead.
Q: How long does the SU 10x4x6.5-SC-EZ tire last and what wear indicators should I monitor?
A: Polyurethane EZ 85A tires typically last 24 to 36 months under normal warehouse use. The softer compound wears faster than XL material, so expect tire replacement sooner in high-mileage operations. Inspect monthly for uneven wear patterns, flat spotting on the crown, or edge feathering which indicates misalignment. Replace when tread depth drops below 0.25 inches or when the tire surface becomes sticky to the touch, indicating compound degradation.
