Frequently Asked Questions
Q: What does the EZ designation mean on SU 631-EZ?
A: The EZ designation typically indicates an easy-installation or simplified design compared to standard SU 631 wheels. This may mean quick-change fasteners, simplified bearing housings, or pre-aligned bolt holes for faster installation. Contact Superior to confirm the specific design improvements. If your truck manual specifies EZ wheels, verify that your truck spindle and axle configuration support EZ-style wheels before ordering.
Q: Is SU 631-EZ compatible with trucks designed for standard SU 631 wheels?
A: SU 631-EZ may have different bolt patterns, bore diameters, or mounting interfaces compared to standard SU 631. Do not assume interchangeability. Verify your truck specifications and compare the SU 631-EZ dimensional drawing against your truck manual. Installing EZ wheels on a non-compatible truck causes installation failures and safety hazards. Contact your truck manufacturer or Superior to confirm compatibility.
Q: What is the load rating for SU 631-EZ?
A: Load capacity for SU 631-EZ is not currently specified. Request the technical data sheet from your supplier or contact Superior directly. The load rating depends on wheel diameter, hub strength, and bearing capacity. Do not exceed the rated load, as this causes accelerated wear and may violate your truck warranty. Check your truck nameplate for maximum load limits and verify the wheel rating matches or exceeds your truck rating.
Q: How is installation of SU 631-EZ different from standard SU 631?
A: If SU 631-EZ includes quick-change fasteners or simplified mounting, installation may be faster than standard SU 631 wheels. Consult the EZ wheel installation guide for specific steps. Do not assume installation is identical to previous wheels. Always follow the manufacturer instructions for torque values and bolt tightening sequence. Even with simplified designs, verify all bolts are torqued correctly after five hours of truck operation.
Q: Should I mix SU 631-EZ with other wheel types on the same truck?
A: No, always use the same wheel type (all SU 631-EZ or all standard SU 631) on all four wheels. Mixing wheel designs causes steering problems and uneven wear. If you are converting from standard SU 631 to SU 631-EZ, replace all four wheels at once. Verify your truck can accept EZ-style mounting before ordering. If you have concerns, consult your truck manual or contact Superior technical support.
