Frequently Asked Questions
Q: What is the difference between SU S529 and SU S529-A?
A: SU S529 is the wheel only (tire and core). SU S529-A is the complete assembly and includes the wheel, bearings, and hub pre-mounted. If you need a bolt-on replacement, order the -A assembly. If you are rebuilding or replacing just the tire, order the wheel only (SU S529).
Q: Is SU S529 (95-A) compatible with SU S529-XL (97-A)?
A: No. SU S529 is 95-A Shore hardness (softer compound for smoother ride and grip on uneven surfaces). SU S529-XL is 97-A Shore hardness (firmer, longer-lasting compound). They are not interchangeable. Use 95-A for rough warehouse floors and 97-A for smooth concrete. Mixing hardness ratings on the same truck creates uneven wear and handling issues.
Q: What are the exact dimensions of SU S529 and does it fit standard 9-inch forks?
A: SU S529 is 3.250 inches (82.55mm) diameter and 6.000 inches (152.40mm) wide. The 6-inch width fits standard 9-inch fork carriages with typical hub spacing. Before installation, verify your carriage bore is 2.047 inches (matching the wheel bore diameter) and measure fork width to ensure 6-inch wheels do not bind at the uprights.
Q: How do I diagnose if SU S529 wheels are worn out?
A: Signs of wear include flat spots on the tread, visible cracking in the polyurethane, reduced grip causing slipping under load, or rumbling noise during operation. Measure the wheel diameter and compare to the original 3.250 inches. If diameter is below 3.0 inches, the wheel must be replaced. Also check for oil or chemical damage, which appears as swelling or softening of the tire surface.
Q: What load capacity should I expect from SU S529 wheels?
A: SU S529 load capacity depends on your complete truck weight rating and wheel assembly design. Do not exceed the truck manufacturer rated capacity. Typical 3.25-inch poly load wheels in warehouses handle 4000-6000 pound per axle loads in dual wheel configurations. Softer 95-A compound (SU S529) is rated for slightly lower sustained loads than 97-A. Always reference your truck manual for maximum load limits.
Q: Can I install SU S529 wheels without removing the carriage from the truck?
A: Yes, in most cases. Jack the truck to full height. Remove the cotter pin and bolt from the wheel axle. Slide the old wheel off and slide the new SU S529 wheel on, ensuring the bore sits square on the axle. Reinstall the bolt and cotter pin. Do not over-tighten the bolt, as this can crush the polyurethane bore. Tighten until snug, then verify the wheel rotates freely.
