Frequently Asked Questions
Q: What are the exact specifications for the SU S145 Hy-Load wheel?
A: The SU S145 is a Hy-Load wheel with nominal dimensions of 3 1/4 inches diameter by 5 7/8 inches width (3.25 x 5.875 inches). Hy-Load is a proprietary elastomer compound designed for increased durability and load capacity in heavy-use environments. Verify exact bore size and mounting type with the OEM, as Hy-Load wheels are often custom configurations.
Q: Can the SU S145 replace my current wheel?
A: The SU S145 is a smaller wheel (3.25 x 5.875) compared to standard 4-inch load wheels. This wheel may not be a direct replacement depending on your truck model. Smaller diameter changes ride height and may affect load capacity. Check your truck manual to confirm the 3.25-inch diameter and 5.875-inch width are compatible before ordering. Do not assume wheel compatibility based on width alone.
Q: What is the load capacity of the SU S145 wheel?
A: Load capacity for the SU S145 depends on the number of wheels supporting the truck and total truck weight. Hy-Load material typically offers higher load capacity per wheel than standard polyurethane, but exact limits depend on your truck configuration. Consult your lift truck documentation for maximum load per wheel. Exceeding rated load damages the wheel and suspension.
Q: How do I install the SU S145 wheel?
A: Lift the truck safely, remove the fastener securing the old wheel, slide the wheel off the axle, align the new SU S145 bore with the axle, and install the original fastener. Ensure the wheel spins freely without rubbing the truck frame. If the bore does not slide onto the axle easily, do not force it, as this indicates incorrect sizing. Torque the fastener per your truck manual.
Q: What is the expected maintenance interval for the SU S145?
A: Inspect the SU S145 monthly for tread wear, cracks, or bearing play. Clean wheel surfaces regularly to prevent dirt buildup. Rotate wheels if your truck design allows it to extend service life. Replace the wheel if you notice flat spots, torn tread, uneven wear, or bearing damage. Proper maintenance can extend service life by 1 to 2 years.
