Frequently Asked Questions
Q: What does tapered side wall mean and why would I choose TSW instead of standard sidewall?
A: Tapered side wall (TSW) means the tire wall gradually reduces in thickness from the bead toward the outer edge. This design improves lateral stability during turning and reduces side wall deflection under load. TSW tires provide more precise steering response and reduced tire roll during cornering. Choose TSW if your operation involves frequent directional changes, tight aisle maneuvers, or if your current tires exhibit excessive bounce or side roll. TSW does not fit all lift trucks; verify your truck accepts TSW profile before ordering.
Q: Is the SU 13 X 4.5 X 8-TSW-EZ cross-compatible with the Crown 79494 tire?
A: Yes, the SU 13 X 4.5 X 8-TSW-EZ cross-references to Crown 79494 (13 x 4.5 x 8 TSW). Both tires share identical dimensions and TSW profile. Use the SU part number for direct ordering as an equivalent replacement. Verify your current tire markings match Crown 79494 before substituting. The SU product provides equivalent performance at competitive pricing compared to the OEM Crown part.
Q: What is X-Groove tread and does the SU 13 X 4.5 X 8-TSW-EZ include it?
A: X-Groove is an optional tread pattern featuring diagonal grooves that channel water and liquid away from the tire surface, improving wet floor traction. The base SU 13 X 4.5 X 8-TSW-EZ features a smooth tread profile. X-Groove variants are available as special order configurations for wet environment applications. If your warehouse has wet floors, slippery conditions, or outdoor wet concrete, request the X-Groove TSW-EZ variant at the time of order.
Q: How does high cut and tear resistance benefit my lift truck operation?
A: High cut and tear resistance means the tire withstands impacts, sharp objects, and rough surfaces without developing cracks or chunks. This is critical for outdoor use, uneven concrete, or facilities with dock ramps and metal gratings. The Cushothane EZ compound in this tire resists punctures and minor impacts better than standard compounds. If your operation involves obstacle-laden floors or aggressive driving, the TSW-EZ profile combined with improved tear resistance provides extended tire life and reduced replacement frequency.
Q: Does the SU 13 X 4.5 X 8-TSW-EZ require any special installation or modification to my current lift truck?
A: The SU 13 X 4.5 X 8-TSW-EZ is a press-on tire that requires no special tools or modifications beyond standard press-on tire installation. If your truck is currently fitted with TSW tires, the new tire removes and installs directly without rim changes. If you are converting from standard sidewall to TSW, confirm your lift truck rim accepts TSW profile. Contact the truck OEM or a lift truck service center to verify compatibility if uncertain. TSW conversion may require rim replacement, which is a dealer service.
