Frequently Asked Questions
Q: Is the SU 12X4.5X8-TSW-EZ compatible with Genie GS-1530 and GS-1932 lift models?
A: Yes. The SU 12X4.5X8-TSW-EZ is confirmed compatible with Genie GS-1530, GS-1532, GS-1930, and GS-1932 scissor lifts and other Superior lift equipment using 12x4.5x8 fitment. Always verify your lift model and serial number range to confirm compatibility before purchase.
Q: What are the cross-reference part numbers for the SU 12X4.5X8-TSW-EZ?
A: Cross-reference equivalents for the SU 12X4.5X8-TSW-EZ include S120045080, SUP31200450802, 1060703/001, and 310025_BC. This tire supersedes and replaces P31200450805 and older SUP31200450802 revisions. If you have existing lift equipment documentation, match against these numbers to confirm direct replacement.
Q: What does TSW tread profile mean and how does it affect performance?
A: TSW stands for tapered side wall. The sides taper inward from the outer edge to the hub, improving lateral stability and steering response compared to flat profile tires. TSW tires provide better grip on turns and reduce side-slip on smooth floors. The tapered design also reduces rolling resistance slightly, which can extend battery range on electric lift trucks.
Q: Is the Cushothane EZ compound non-marking on warehouse floors?
A: Yes. The SU 12X4.5X8-TSW-EZ is constructed from non-marking Cushothane EZ material, which will not leave black scuff marks on clean floors or carpeted areas. This is critical for indoor retail and office environments where floor appearance matters. Verify compatibility with your floor type before deployment, as some specialty coatings may react differently.
Q: How long does the Cushothane EZ compound typically last before replacement is needed?
A: Cushothane EZ polyurethane typically lasts 3-5 years under normal warehouse duty cycles. Lifespan depends on load weight, floor conditions, and hours of daily use. Check for visible cracking or uneven wear every 6 months. Replace immediately if wear reaches the hub or if you observe chunks missing from the tire edge.
Q: Can I mix TSW and smooth-flat tires on the same lift truck?
A: Do not mix tire profiles on the same truck. Mismatched profiles cause uneven handling and steering pull. Replace all four tires with the same profile type. If upgrading from smooth-flat to TSW, plan for a full set replacement.
