Frequently Asked Questions
Q: What are the key specifications of the SU S854 load wheel?
A: The SU S854 is a polyurethane load wheel with 5.000 inch outside diameter and 2.875 inch tread width. The bore diameter is 2.25 inch inside with a 2.4404 inch bore outside diameter for mounting. Material is Cushothane XL, a premium polyurethane compound. The 3/8 radius tread profile provides grip in wet and dry conditions. Hub width is 2.875 inch with a bore depth of 0.817 inch.
Q: How does the SU S854 compare to the SU S854-A and SU S854-XL?
A: The SU S854 is the wheel component only, while SU S854-A is the complete wheel assembly with bearing and hub. The SU S854-XL designation indicates an extra-load or extended-wear Cushothane material formulation. If you need just the wheel elastomer, order SU S854. If you need a ready-to-install assembly, order SU S854-A or SU S854-XL-A. Verify which component you need before ordering.
Q: What is the maximum load rating and ambient temperature range for the SU S854?
A: Cushothane XL polyurethane wheels typically support 500-800 pounds per wheel depending on vehicle configuration. Operating temperature range is minus 20 degrees Fahrenheit to plus 130 degrees Fahrenheit. In freezer environments below minus 10 degrees Fahrenheit, polyurethane wheels harden and may reduce grip. Verify the total vehicle load and wheel configuration with your manufacturer to confirm the SU S854 is rated for your application.
Q: Can the SU S854 wheel be used as a replacement if the bore diameter is slightly different?
A: No. The SU S854 has a 2.25 inch inside bore diameter and 2.4404 inch bore outside diameter. Bore mismatch will cause wobbling, rapid wear, and bearing failure. If your truck uses a different bore diameter, you must order the correct part number. Do not use shims or spacers to make a mismatched wheel fit; this creates a safety hazard and voids the warranty.
Q: How do I diagnose if the SU S854 wheel needs replacement?
A: Lift the truck and spin the wheel by hand. Listen for grinding or feel for resistance, which indicates bearing wear. Check for visible cracking, chunking, or flat spots in the polyurethane tread. Measure tread depth with calipers; replace when depth drops below 50 percent of original. If the wheel wobbles or moves side-to-side on the spindle, the bearing is damaged and the assembly must be replaced.
Q: What is the shelf life and storage requirement for the SU S854?
A: Polyurethane wheels maintain integrity for 3-5 years in a dry storage environment (50-70 degrees Fahrenheit, below 60 percent humidity). Store wheels indoors away from direct sunlight and sources of heat or oil. Do not stack wheels more than 4 high to prevent deformation. Once installed on the truck, typical operating lifespan is 12-24 months depending on load and environment intensity.
