Frequently Asked Questions
Q: What is a tapered side wall (TSW) load wheel and how does it differ from a smooth flat tire?
A: A tapered side wall slopes inward from the outer edge to a narrower inner bore, allowing the wheel to straddle the load wheel castings without binding. Load wheels support the truck frame and load during travel; drive wheels power movement. The TSW profile is essential for load wheel function. Do not use a smooth flat drive tire as a load wheel; it will damage the casting assembly.
Q: Is the SU 10.5 X 4 X 8-TSW-P compatible with 5000 lb capacity forklifts?
A: Yes, for most standard 5000 lb class forklifts. The 10.5 inch diameter and 4 inch width are common load wheel sizes. Verify your truck manual specifies a 10.5 x 4 load wheel with an 8 inch hub bore. Some truck models use 10 x 4.5 or 9.5 x 4 alternatives. Confirm the exact size before ordering to avoid fitment issues.
Q: Can I reuse an old hub assembly when replacing a worn load wheel?
A: Only if the hub bore is intact and measures exactly 8 inches. Have a technician inspect the bearing fit; if worn or loose, the new tire will wobble and fail early. Check for cracks or bent castings. If any damage is present, order a complete hub assembly. A damaged hub cannot support proper wheel tracking and is a safety hazard.
Q: What is the expected service life of a polyurethane load wheel in warehouse operation?
A: Typically 18-24 months in moderate indoor warehouse duty (pallet movement, smooth concrete). Life depends on floor cleanliness (debris accelerates wear) and load distribution. Heavily loaded trucks or rough outdoor surfaces reduce life to 12-18 months. Stop using the wheel if flats appear, the tire feels sticky or hardened, or the truck pulls to one side while traveling empty.
Q: How do I identify when a load wheel needs replacement?
A: Visual inspection: flat spots, chunks missing from the tread, or visible cracking. Operational: the truck drifts unexpectedly, the steering wheel is hard to turn, or the wheel makes a grinding sound during turns. Hardness test: press thumb into the tire surface; if it does not spring back within 3 seconds, the material is aged and should be replaced. Never attempt to re-tread a load wheel.
Q: What tools and procedure are required to install a new load wheel?
A: Tools: hydraulic press (5-10 ton), wheel puller, safety gloves, torque wrench. Steps: (1) Lift truck on blocks. (2) Remove hub assembly bolt and pull hub from axle. (3) Press old tire off hub, clean bore. (4) Press new tire onto hub, ensuring tapered side seats properly in bore. (5) Align wheel before reinstalling. (6) Torque hub bolt to manufacturer spec (typically 40-60 ft-lbs). (7) Verify wheel rolls freely with no wobble.
