Frequently Asked Questions
Q: What is the difference between SU S653-EZ-A and SU S653-A?
A: Both are complete polyurethane wheel assemblies for tandem configuration. SU S653-EZ-A and SU S653-A both include the wheel core and mounting hardware. The core specifications are identical: 5.000 inch diameter x 2.875 inch width, 1.87 inch bore. Both are direct replacements for each other. Use the SKU listed on your original wheel to order an exact match replacement.
Q: Does SU S653-EZ-A include axle bolts and washers?
A: Yes, SU S653-EZ-A includes complete mounting hardware for fork installation. Hardware typically includes two axle bolts, washers, and lock washers. Verify hardware condition upon receipt; if bolts are damaged or corroded, replace them before installation. Use stainless steel hardware in wet environments to prevent corrosion and binding.
Q: Can I install SU S653-EZ-A wheels on left and right sides of the same truck?
A: Yes, SU S653-EZ-A wheels are symmetric and can be installed on either side. For balanced operation, always replace wheels in pairs or quads (both left and right, or all four if quad configuration). Installing a new wheel on one side only causes uneven handling, pulling, and unequal load distribution. This accelerates wear on the older wheel and stresses steering linkage.
Q: What is the maximum load per wheel for SU S653-EZ-A in tandem configuration?
A: Load capacity is determined by truck model, not the wheel alone. Tandem wheels on typical 3000-pound trucks carry approximately 750-1500 pounds per wheel. Do not exceed your truck manufacturers rated load. Overloading causes polyurethane tread to degrade, hub cracking, and bearing failure. Check the truck nameplate for exact load limit.
Q: How do I check if SU S653-EZ-A is wearing evenly?
A: Inspect tread depth across the wheel width. Even wear shows uniform thickness from edge to edge. Uneven wear (one edge thinner) indicates axle misalignment or overloading. Use a depth gauge to measure tread. If one wheel wears 30 percent faster than its pair, check axle bolt torque (should be 15-18 foot-pounds) and truck frame alignment. Uneven wear reduces wheel life by 40-50 percent.
Q: What maintenance does SU S653-EZ-A require?
A: Monthly: Clean polyurethane tread of debris and check for cracks or separation from hub. Quarterly: Verify axle bolt torque at 15-18 foot-pounds. Annually: Measure tread depth and inspect bore for corrosion. Store spare assemblies in cool, dry conditions away from ozone sources (electrical equipment, welders). Do not use solvents or harsh chemicals on polyurethane; use mild soap and water only.
