Frequently Asked Questions
Q: What does the P designation mean and how does it compare to XL or EZ compounds?
A: The P designation indicates premium industrial-grade polyurethane at a mid-range durometer, balancing durability with operational efficiency. The P compound performs between the soft EZ 85A and hard XL 97A options. It provides good wear resistance, reasonable cut and tear protection, and acceptable rolling efficiency for general warehouse use. Use P compound for mixed-duty applications where you need versatility without specializing for extreme conditions.
Q: Is the 3/8 inch steel ring base bonded to the tread or is it replaceable?
A: The 3/8 inch steel ring is permanently bonded to the polyurethane tread using industrial adhesive and cannot be separated or replaced. When the tire is worn, the entire assembly must be discarded and replaced with a new tire. This design ensures a permanent, reliable interface between the tread and rim. Do not attempt to separate the steel ring from the tread; doing so compromises the structural integrity and safety of the tire.
Q: Can I use the SU 13 X 4.5 X 8-SF-P on an older Crown lift truck with a different rim specification?
A: No. The SU 13 X 4.5 X 8-SF-P is engineered specifically for standard 8-inch inner diameter rims found on Crown and similar modern lift trucks manufactured after 2005. Older Crown trucks (pre-2000) may use 6-inch or 7-inch rims that require different tire sizes. Always verify your current rim diameter before ordering. Attempting to force an 8-inch tire onto a 6-inch rim will not seat properly and creates a safety hazard.
Q: What maintenance steps should I follow to maximize tire lifespan?
A: Perform monthly inspections: check tire pressure if your tire has pressurized components, inspect for visible cracks or chunks, and verify the tire seats properly on the rim. Keep the warehouse floor clean to minimize cut and abrasion hazards. Rotate tires every 6-12 months if your operation permits rotation between multiple trucks. Avoid sustained operation with under-load conditions or excessive turning radius, as this accelerates wear. Maintain lift truck alignment to prevent uneven tire wear.
Q: Is this tire suitable for use in food processing or pharmaceutical warehouse environments?
A: The SU 13 X 4.5 X 8-SF-P is constructed from synthetic polyurethane and does not contain natural rubber or allergens common in latex. It is compatible with food and pharmaceutical warehouse environments from a contamination standpoint. However, verify that your facility does not require food-grade certification or specific regulatory compliance for lift truck tires. Always confirm with your facility manager and consult any applicable FDA or industry standards before deploying in sensitive environments.
