Frequently Asked Questions
Q: What does SC-EZ mean on the SU 10X4.75X6.5-SC-EZ tire part number?
A: SC denotes a crowned (convex) profile, which improves tracking and traction on uneven floors. EZ indicates Cushothane EZ 85A material, a softer, more flexible polyurethane formulation designed for shock absorption on concrete. This combination makes the SC-EZ suitable for rougher warehouse floors, outdoor use, and longer-distance transport compared to solid rigid polyurethane.
Q: Is SU 10X4.75X6.5-SC-EZ compatible with SU 10X4.75X6.5-SF-P tires on the same truck?
A: Both tires have identical 10 inch diameter and 4.75 inch width, and can fit the same 6.5 inch wheel. However, do not mix profiles on the same axle. Install crowned tires (SC-EZ) on both front or rear wheels of the same axle. Mixing crowned and smooth profiles on one axle causes the truck to pull and creates uneven load distribution, accelerating wear.
Q: How long does the softer Cushothane EZ 85A material last compared to rigid polyurethane?
A: Cushothane EZ 85A is softer and compresses more, absorbing shock better but wearing faster on high-volume surfaces. Expect 12 to 24 months of service life in moderate duty, compared to 18 to 36 months for rigid polyurethane. EZ material is best for choppy outdoor floors, ramps, and light towing. On smooth indoor floors, rigid polyurethane lasts longer.
Q: What surface conditions are best for the crowned profile on the SU 10X4.75X6.5-SC-EZ?
A: The crowned profile excels on uneven, cracked, or porous concrete; outdoor asphalt; and ramps. It provides better edge grip and reduces tilting. Avoid very smooth, flat polished concrete or floors with deep grooves or cracks larger than 0.5 inches, as the tire crown can catch and cause steering issues. Test the tire on your specific floor type before ordering a full set.
Q: Can I replace only one wheel with SU 10X4.75X6.5-SC-EZ if the others are worn?
A: No. Always replace tires in sets of two per axle (front pair or rear pair). Installing one new tire with a worn tire on the same axle creates diameter mismatch and causes the truck to pull. If you must replace one wheel, also replace its pair, even if slightly worn. This maintains load balance and steering control.
Q: How do I tell if SU 10X4.75X6.5-SC-EZ is worn out or failing?
A: Watch for chunks missing from the crown (center), cracks running parallel to the wheel, or a flattened crown that no longer has a curve. If the tire slips on floors it previously gripped, or if steering feels spongy or delayed, the cushioning material is failing. Also check for edge separation or peeling. Replace immediately if any of these signs appear to prevent loss of control.
