Frequently Asked Questions
Q: What are the dimensions of the SU 459-A load wheel?
A: The SU 459-A load wheel measures 6.000 inch diameter by 3.000 inch width. The bore diameter is 2.4404 inch OD with a 0.78 inch bore depth and 2.25 inch ID. Metric equivalent is 152.40mm diameter by 76.20mm width. The 3/8 inch radius tread profile provides optimal grip on concrete and smooth floors.
Q: What material is the SU 459-A made from?
A: The SU 459-A uses Cushothane XL polyurethane, a premium high-duty-cycle material formulated for extended wear and load capacity. The wider 3 inch width spreads loading across more contact area, reducing per-unit pressure on the tire surface and extending service life compared to narrower wheels on the same truck.
Q: What truck models accept a 6 x 3 load wheel like the SU 459-A?
A: Six by three load wheels fit wide-stance electric lift trucks designed for stability on uneven floors or for heavier load profiles. Common models include certain Toyota, Crown, Raymond, and Hyster platforms. Do not assume the 6 x 3 fits your truck based on diameter alone. Verify the original wheel width and bore size match specifications before ordering.
Q: How do I know if my truck needs a 6 x 3 wheel instead of a narrower option?
A: If your truck currently uses a 6 inch diameter wheel with approximately 3 inch width, the SU 459-A is the correct replacement. If your truck has a narrower wheel (such as 6 x 2 or 6 x 2.5), do not install the SU 459-A. Mixing wheel widths causes binding on the axle or insufficient load distribution. Match the existing width exactly.
Q: What is the typical load capacity of a 6 x 3 wheel?
A: A 6 x 3 wheel typically supports 3,000 to 6,000 pounds depending on truck design and bearing specifications. The wider contact patch of the 3 inch width distributes weight more evenly than narrower wheels. Refer to your truck load plate for exact rated capacity. Never exceed the truck manufacturer rating regardless of wheel size.
Q: How often should I inspect the SU 459-A for wear?
A: Inspect the SU 459-A quarterly or every 500 operating hours, whichever comes first. Look for flat spots on the tread, edge chipping, bore cracking, or visible material separation. Measure diameter at multiple points. Replace when diameter loss exceeds 0.125 inch or when bore clearance becomes visibly loose. Replace both wheels as a pair to prevent steering issues.
