Frequently Asked Questions
Q: Is the SU S393-EZ a direct replacement for the SU S393-XL wheel?
A: The S393-EZ and S393-XL are both 9 x 5 wheels, but they use different polyurethane formulations: EZ is softer/more elastic while XL is harder. Do not mix these wheels on the same truck; they have different load ratings and ride characteristics. Verify your current wheel marking or consult the truck documentation to determine which material type your truck requires before purchasing.
Q: What is the exact diameter and width of the SU S393-EZ?
A: The SU S393-EZ is 9.000 inches outside diameter by 5.000 inches width (228.60mm x 127.00mm). Bore depth is 0.787 inch and hub bore outside diameter is 3.5433 inch. These dimensions are nominal; verify against your existing wheel to confirm compatibility before ordering, as axle diameters vary across truck models.
Q: What does Cushothane EZ material mean and why does it matter?
A: Cushothane EZ is a softer, more elastic polyurethane formulation (typically 90-95A durometer) designed to absorb shock and provide a smoother ride on rough floors. EZ wheels wear faster than XL wheels but offer better traction and less vibration. Use EZ on uneven concrete or outdoor surfaces; use XL for smooth warehouse floors where durability is prioritized over comfort.
Q: How do I know if my truck uses a wheel with a 3.5433 inch hub bore?
A: Remove one wheel from your truck and measure the axle bolt hole diameter or the center bore diameter of the hub. If it measures 3.543 inches (approximately 90mm), the S393-EZ hub will fit. If your hub bore is 2.165 inch or smaller, the S393-EZ will not fit and you need a different part number. Always cross-reference your truck model year and serial number with the parts diagram.
Q: Can the SU S393-EZ be repaired or must it be replaced?
A: The S393-EZ cannot be repaired. If the wheel develops cracks, chunks missing, or flat-spotting (surface depression of 0.25 inch or greater), the wheel must be replaced. Attempting to use a damaged wheel risks losing load control and can cause truck instability. Replace immediately upon detection of damage.
Q: What is the typical lifespan of the SU S393-EZ in a busy warehouse?
A: The SU S393-EZ typically lasts 18-36 months under continuous warehouse use (6+ hours daily). Lifespan is shorter than XL wheels due to softer material. Replace when tread depth reduces visibly, flat-spots exceed 0.25 inch, or the wheel no longer rolls smoothly. Inspect quarterly and budget for replacement annually in high-use environments.
