Frequently Asked Questions
Q: What is the load capacity and durometer rating for the SU 12X4.5X8-SF-XL?
A: The SU 12X4.5X8-SF-XL is a Cushothane XL polyurethane drive tire with a 97A durometer rating. This higher durometer rating provides superior wear resistance and load capacity compared to softer compounds. Load capacity depends on your lift truck model and tire configuration. Verify the maximum load rating with your equipment documentation before exceeding standard duty cycles.
Q: Is the SU 12X4.5X8-SF-XL compatible with pneumatic tire applications or only solid press-on?
A: The SU 12X4.5X8-SF-XL is a solid press-on polyurethane tire, not pneumatic. Do not attempt to inflate this tire. The solid construction eliminates flat tire issues and requires no maintenance related to air pressure. It is designed for press-on mounting onto an 8-inch hub bore only.
Q: What is the replacement interval and maintenance for the SU 12X4.5X8-SF-XL?
A: Press-on polyurethane tires typically last 2-4 years depending on floor conditions and load cycles. Maintenance is minimal: keep tires clean and check for visible cracking or chunking every 6 months. Replace tires immediately if you observe wear through to the hub or uneven wear patterns indicating misalignment.
Q: Can I use the SU 12X4.5X8-SF-XL on wet concrete or smooth warehouse floors without slipping?
A: The smooth flat profile of the SU 12X4.5X8-SF-XL provides moderate grip on standard concrete. On wet floors, grip is reduced compared to treaded tires. For slippery surfaces, consider switching to a TSW (tapered side wall) or textured tread profile. Test handling in your specific environment before committing to full fleet replacement.
Q: What dimensions must I verify before ordering the SU 12X4.5X8-SF-XL?
A: Confirm three critical dimensions: outside diameter 12.000 inches (304.80mm), width 4.500 inches (114.30mm), and hub bore 8 inches. Measure your existing tire and hub to verify fitment. An incorrect bore size will not press-on correctly. Cross-check your lift truck model documentation to confirm the 12x4.5x8 is the correct size before ordering.
Q: How does the Cushothane XL 97A compound compare to standard polyurethane on pallet jacks?
A: Cushothane XL at 97A durometer is harder and more wear-resistant than standard 85A polyurethane, especially in high-cycle environments or rough dock areas. The tradeoff is reduced vibration damping and slightly less grip on wet surfaces. Use XL for outdoor or heavy-duty indoor operations; switch to softer compounds if operator comfort is a priority.
