Frequently Asked Questions
Q: What is the load rating for the SU 13.5X5.5X8-SF-R-SIPED siped rubber wheel?
A: The SU 13.5X5.5X8-SF-R-SIPED is rated for electric lift truck drive applications with standard duty loads up to 4000 lbs per wheel pair, depending on the jack model. Always verify your specific truck weight capacity in the operator manual before installation. Siped tread provides improved traction in wet or slippery warehouse floors.
Q: Is the SU 13.5X5.5X8-SF-R-SIPED compatible with my Toyota or Crown pallet jack?
A: The SU 13.5X5.5X8-SF-R-SIPED with 13.5 inch OD and 5.5 inch width fits electric jacks requiring this exact dimension. Toyota and Crown models with 13.5x5.5x8 bore spec are compatible. Cross-reference your jack manual for the OEM part number first. If your jack uses a different bore diameter or width, this tire will not mount correctly.
Q: How do I install the SU 13.5X5.5X8-SF-R-SIPED press-on wheel?
A: Press-on tires require heating or a tire press to mount onto the hub. Heat the tire to approximately 140-160 degrees Fahrenheit using a tire oven or heat gun, then slide it onto the 8-inch bore hub while hot. Allow 30 minutes cooling time before operating. Do not use mechanical force or hammering as this can damage the rubber compound. A tire mounting press is the safest method.
Q: What are the signs that my SU 13.5X5.5X8-SF-R-SIPED tire needs replacement?
A: Replace the siped rubber tire if you observe: uneven wear patterns, flattening at the siped edges, loss of tread definition, visible rubber chunking or separation, or diameter wear exceeding 0.5 inches. Inspect quarterly for cracks or hardening. Siped tires typically last 18-36 months depending on warehouse conditions and load duty.
Q: What is the diameter and width of the SU 13.5X5.5X8-SF-R-SIPED?
A: Outside diameter is 13.500 inches (342.90 mm). Width is 5.500 inches (139.70 mm). Bore diameter is 8.000 inches. The smooth flat drive profile with siped tread is designed for electric lift truck applications requiring reliable traction and load support.
Q: Can I substitute the SU 13.5X5.5X8-SF-R-SIPED with a non-siped rubber tire?
A: Yes, if your facility does not require the extra traction of a siped tire, a smooth rubber tire with the same dimensions will mount and function correctly. However, siped tires provide superior grip on wet or oily concrete, reducing wheel slip and improving steering control. If your warehouse is predominantly dry, either tire type will work, but siped offers better safety margins.
