Frequently Asked Questions
Q: How does the SU 13 X 4.5 X 8-TSW-P differ from the TSW-EZ in terms of load capacity and durability?
A: The SU 13 X 4.5 X 8-TSW-P uses industrial-grade premium polyurethane with a mid-range durometer that provides better cut and tear resistance than the softer EZ compound while maintaining better efficiency than the hard XL compound. The P compound is engineered for sustained heavy loading without premature compound breakdown. While both tires fit the same rim, the TSW-P is optimized for continuous heavy-duty warehouse operation with maximum load cycles per day. Choose TSW-P if your lift truck consistently carries maximum rated load.
Q: Can I install the SU 13 X 4.5 X 8-TSW-P tire on a lift truck not specifically designed for TSW profile?
A: No. The TSW profile is engineered to fit specific lift truck rims designed with tapered geometry. Installing a TSW tire on a standard (non-tapered) rim results in improper seating, tire wobble, and potential bead separation. This creates a serious safety hazard and voids the tire warranty. Always verify that your lift truck rim is designed for TSW profile before ordering. If your truck uses standard rims, order the SU 13 X 4.5 X 8-SF-P flat sidewall tire instead.
Q: What does surface ground for uniform traction mean and how does this affect performance?
A: The tread surface is precision-ground after manufacturing to ensure perfectly uniform contact with the floor. This eliminates surface irregularities and provides consistent grip across the entire tire face. Uniform grinding reduces flat-spotting during prolonged storage or when the truck is parked under load. The result is more predictable traction, better steering response, and more even tire wear. The grinding process is a premium manufacturing step that increases durability and extends operational lifespan.
Q: Is the precision-machined steel core on the SU 13 X 4.5 X 8-TSW-P bonded permanently to the polyurethane?
A: Yes, the precision-machined steel core is permanently bonded to the polyurethane tread assembly using industrial adhesive during manufacturing. The bond cannot be disassembled. The steel core provides structural rigidity and supports the polyurethane tread under load. Do not attempt to separate the core from the tread. When the tire reaches end of life, the entire assembly must be replaced as a unit.
Q: What is the OEM part number and does this tire work with lift trucks other than the stated applications?
A: The OEM part number is SU 13 X 4.5 X 8-TSW-P. This tire is engineered for standard 8-inch rim ID lift trucks from Crown, Yale, Hyster, Mitsubishi, Toyota, and equivalent manufacturers. However, verify your specific truck model accepts TSW profile tires. Older trucks or specialty models may use different rim specifications. Cross-reference your current tire marking to the 13 x 4.5 x 8 TSW specification. If your truck uses a different size, do not attempt force-fitting; order the correct size for your truck model.
