Frequently Asked Questions
Q: Is SU S653-XL-A a complete wheel assembly, and does it include hardware?
A: Yes, SU S653-XL-A is a complete polyurethane tandem wheel assembly. It includes the wheel core with Cushothane XL tread, bonded to a steel hub, plus all mounting hardware (axle bolts, washers, and lock washers). No additional parts are needed for installation. Verify hardware condition upon receipt; replace corroded or damaged bolts before installation.
Q: What is the difference between SU S653-XL-A and SU S653-EZ-A?
A: SU S653-XL-A uses Cushothane XL material and optimized bonding for extended durability and mid-market industrial applications. SU S653-EZ-A uses standard Cushothane XL in a simpler assembly. Both are 5.000 inch x 2.875 inch and fit the same forks. SU S653-XL-A lasts longer (18-30 months vs. 12-24 months) and costs more. Choose SU S653-XL-A for high-use or harsh-condition trucks.
Q: Can SU S653-XL-A wheels be used in tight-turning dual and triple configurations?
A: Yes, SU S653-XL-A is designed for dual and triple wheel assemblies. The Cushothane XL tread provides superior grip for frequent direction changes. Use SU S653-XL-A in pairs (both sides) or quads (all four wheels) for balanced handling. Installing a single wheel among standard wheels causes uneven wear and steering instability.
Q: What torque specification should I use when installing SU S653-XL-A?
A: Tighten axle bolts to 15-18 foot-pounds. Over-tightening above 20 foot-pounds risks cracking the steel hub and hub bore. Under-tightening below 12 foot-pounds allows wheel slippage and binding during operation. Use a calibrated torque wrench. Recheck bolt torque after 8 operating hours and monthly thereafter. Lock washers prevent bolt loosening during heavy use.
Q: How do I know if SU S653-XL-A is wearing correctly?
A: Inspect tread for even wear across the full width. Flat spots, one-sided wear, or tread separation indicate misalignment or overloading. Use a depth gauge to check tread thickness at multiple points. Measure wear every 500 operating hours. If tread wears 30 percent faster on one side, check axle bolt torque and truck frame alignment. Uneven wear reduces remaining wheel life by 40-50 percent.
Q: What is the expected service life of SU S653-XL-A in heavy-duty operation?
A: In standard warehouse operation (8-10 hours per day, normal loading), SU S653-XL-A lasts 18-30 months. In heavy-duty service (12-16 hours per day, frequent turning, overloading), expect 12-18 months. Cold environments below 40 degrees Fahrenheit reduce polyurethane flexibility and life by 20 percent. Store spare assemblies in cool, dry conditions. Replace wheels as a set to maintain balanced performance.
