Frequently Asked Questions
Q: What cross-references are equivalent to the SU S629-XL?
A: The SU S629-XL is equivalent to the original S629, L500629, and L500629A1 parts designated by Superior Tire. The SU S629-XL replaces all three older part numbers. Verify bore diameter (2.0467 inches) and hub width (5.873 inches) match your jack before cross-referencing. Do not assume all S629 variants are interchangeable.
Q: How does the SU S629-XL with 97A hardness differ from the 87A SU S629-EZ?
A: The SU S629-XL uses 97A Shore hardness Cushothane XL instead of 87A, providing 30-40 percent greater tear resistance and resistance to abrasive floors. The 97A compound lasts 50 percent longer in high-traffic environments. Trade-off is slightly reduced traction on smooth floors and marginally higher floor noise.
Q: What is the XL3 bonding technology used in the SU S629-XL?
A: XL3 is a premium bonding agent applied to the precision-finished steel hub before polyurethane molding. It prevents tread separation and delamination caused by mechanical shock, thermal cycling, and chemical exposure. XL3 bonding ensures the polyurethane stays bonded to the hub throughout the wheel service life.
Q: Can I repair or resurface a SU S629-XL wheel if the tread is worn flat?
A: No. Polyurethane wheels cannot be resurfaced, turned, or retreaded. Once the tread is flat or exhibits cracks, the entire wheel must be replaced. Attempting to repair it damages the XL3 bond and creates safety hazards. Replace all four wheels at the same time to maintain balanced handling.
Q: What floor conditions are the SU S629-XL wheels rated for?
A: The SU S629-XL is rated for indoor warehouse floors, concrete, polished epoxy, and vinyl surfaces. Do not use on outdoor asphalt, gravel, or wet surfaces, which accelerate polyurethane degradation. The 97A hardness is unsuitable for extremely smooth floors where grip is critical. Verify floor type matches wheel compound before purchase.
