Frequently Asked Questions
Q: What are the dimensions and tread profile of the SU 13.5x6.5x8-SC-P?
A: The SU 13.5x6.5x8-SC-P is 13.500 inches diameter by 6.500 inches width (metric: 342.90mm by 165.10mm). SC means smooth crown profile, which is slightly rounded in the center to improve load distribution and tracking on equipment like walkie stackers and pallet jacks.
Q: What is the difference between smooth crown and smooth flat wheel profiles?
A: Smooth crown wheels have a rounded center profile that provides better load-sharing and self-centering on the axle, reducing edge wear. Smooth flat wheels have a level surface and work better on equipment where the wheel is fully supported across its width. Crown profile improves maneuverability on lift trucks.
Q: Is the SU 13.5x6.5x8-SC-P compatible with my electric pallet jack?
A: The SU 13.5x6.5x8-SC-P fits electric pallet jacks and small lift trucks requiring a 13.5 inch wheel with 6.5 inch width. Verify the axle size, steering mechanism type, and current wheel width on your equipment before ordering. Some axles have width limits due to bearing spacing.
Q: How do I know when the polyurethane wheel needs replacement?
A: Replace wheels when the tread is visibly worn flat, the crown profile is lost, the wheel has chunks or cracks, or steering becomes sluggish. Worn polyurethane wheels lose grip, especially on wet floors, and can damage your warehouse flooring. Do not wait until the wheel is severely damaged.
Q: What polyurethane hardness is the SU 13.5x6.5x8-SC-P and where should I use it?
A: The SU designation indicates standard polyurethane durometer. This hardness is suitable for indoor warehouse use on concrete floors. Polyurethane is gentler on flooring than rubber and provides good grip without marking. Not recommended for outdoor or wet environments where rubber or cushothane compounds perform better.
Q: Are there equivalent wheels from other manufacturers for the SU 13.5x6.5x8-SC-P?
A: Cross-reference the axle hub size, bolt pattern, and wheel width to find equivalents from Yale, Crown, Mitsubishi, or other lift truck manufacturers. Wheels must match the axle bore diameter and fit within the equipment frame width. Contact your equipment dealer with your model number for verified equivalent part numbers.
