Frequently Asked Questions
Q: What does the EZ designation mean on the SU S9149-EZ wheel?
A: EZ indicates a High Traction polyurethane compound engineered specifically for challenging floor conditions. The EZ compound is optimized for wet floors, cold storage environments, and operations with expanded temperature ranges. It does not refer to ease of installation. The 85 Shore A tread hardness provides enhanced grip on slippery surfaces compared to softer compounds, reducing slip hazards in freezers and wet areas.
Q: Can I use the SU S9149-EZ wheel in dry warehouse environments?
A: Yes. While the SU S9149-EZ is designed for wet and cold storage applications, it performs adequately in dry warehouses. The High Traction compound will provide good grip even on clean, dry concrete. However, if your truck operates exclusively in climate-controlled, dry facilities, a softer compound may offer better wear life and lower rolling resistance. Consider application mix before purchasing.
Q: What is the core material and how does it affect performance?
A: The SU S9149-EZ features a high-strength nylon core with precision ball bearing seat. The nylon core is lighter than steel and resists corrosion in cold storage and wet environments. The precision bearing seat ensures the bearing stays centered and properly supported under load, reducing noise and extending bearing life. This design is ideal for repetitive, continuous rolling service in demanding warehouse conditions.
Q: How do I diagnose if this wheel is damaged or failing?
A: Watch for visible cracks, chunks missing from the tread, or a flat spot on the wheel surface. Spin the wheel by hand; a damaged bearing will produce grinding noise or resistance. In operation, listen for squealing and feel for vibration in the handle. If the truck pulls to one side despite straight steering input, a flat or worn wheel on one side may be causing uneven weight distribution.
Q: Is the SU S9149-EZ suitable for outdoor operations in winter?
A: Yes. The polyurethane compound remains flexible at low temperatures that would harden soft rubber compounds, and the High Traction profile maintains grip on ice and snow. However, salt and chemical deicing agents can degrade polyurethane over time. Rinse the wheels periodically with fresh water after outdoor winter use to extend service life.
Q: What maintenance extends the life of the SU S9149-EZ wheel?
A: Inspect wheels monthly for debris buildup, cracks, or tread separation. Keep the bearing seat clean and check that the bearing spins freely. In wet or cold storage, clean wheels with fresh water to remove salt residue and ice buildup. Ensure proper truck tire pressure equivalent and load balance across all wheels. Replace wheels when tread depth falls below 50 percent of original or if you observe any core separation from the tread.
