Frequently Asked Questions
Q: What Crown part numbers does the SU 10x4x6.5-SF-R replace?
A: The SU 10x4x6.5-SF-R cross-references to Crown 127251-201-42 (traction compound) and Crown 357251-402-41 (smooth compound). Verify which version your truck requires, as traction and smooth compounds have different grip characteristics and are not interchangeable for warranty purposes.
Q: Is the SU 10x4x6.5-SF-R a press-on or bonded tire?
A: The SU 10x4x6.5-SF-R is a press-on solid airless construction with a bonded 3/8 inch steel press-on ring. The steel ring is permanently bonded to the tire and must be pressed onto the 6.5 inch mounting bore. This design is more durable than bonded rubber-only tires for high-cycle operations.
Q: What compound should I choose, traction or smooth, and how do they differ?
A: Traction compound provides higher grip on smooth concrete but may mark floors slightly. Smooth compound has lower rolling resistance and is non-marking but offers reduced traction on wet or sloped surfaces. For general warehouse use, traction is more common. For freezers or wet environments, smooth reduces slippage risk.
Q: How do I remove and install the SU 10x4x6.5-SF-R on the wheel hub?
A: Removal requires a tire puller or press. Do not pry with a screwdriver; this damages the hub. Installation requires a tire press to push the tire onto the hub until the steel ring seats fully. Improper seating causes vibration and uneven wear. Press force is typically 8-12 tons. Always verify hub bore size is exactly 6.5 inches before pressing.
Q: What is the typical replacement interval for the SU 10x4x6.5-SF-R?
A: In continuous 8-hour-per-day warehouse use, replace every 3-4 years. The steel press-on ring extends tire life compared to bonded-only designs. Inspect quarterly for uneven wear, sidewall cracking, or separation between the rubber and steel ring. Any separation requires immediate replacement to prevent wheel instability.
