Frequently Asked Questions
Q: Is SU 9X5X5-TSW-EZ-A compatible with other TSW profile drive tires from different manufacturers?
A: SU 9X5X5-TSW-EZ-A is a Tapered Side Wall profile drive tire at 9x5 inches with an 85 Shore A polyurethane tread. Cross-compatibility depends on the mounting core type and profile. Always verify the mounting bore and press-fit core diameter with your OEM documentation. Do not assume fit based on diameter and width alone. The TSW EZ designation is specific to this tire series and may not interchange with standard TSW or other profiles.
Q: What is the difference between the 85 Shore A polyurethane in SU 9X5X5-TSW-EZ-A and a higher durometer compound?
A: The 85 Shore A durometer provides a softer, more grip-optimized tread for electric lift truck drive applications. Higher durometer compounds (90A, 93A) are harder and wear longer but provide less traction. Lower compounds (80A or less) wear faster. For dry indoor warehouse use, 85 Shore A provides the best balance of traction and tread life. If you experience slipping on wet or oily floors, you cannot compensate by changing durometer without risk of uneven wear or core damage.
Q: How do you diagnose if an SU 9X5X5-TSW-EZ-A tire needs replacement?
A: Monitor for these symptoms: visible flat spots or chunking on the tread surface, reduced grip causing wheel slip during acceleration or on inclines, and tread wear to less than 1 inch depth. Press-on tires cannot be retreaded. If the core is damaged or the tread separates, the entire assembly must be replaced. Failure to replace a worn drive tire will cause the truck to lose traction and may damage the motor due to wheel slip feedback.
Q: What installation tools and precautions are required for mounting an SU 9X5X5-TSW-EZ-A tire?
A: This tire uses press-on steel core construction and requires a tire press with a minimum press force of 4 to 6 tons. Do not use manual mounting tools or dead-blow hammers as this damages the core and tread bond. Verify the core bore diameter and hub shaft diameter match exactly before pressing. Apply light machine oil or assembly lubricant to the core bore to ease installation. After mounting, allow the tire to settle for 24 hours before operating the truck.
Q: What are the maximum load and speed ratings for a 9x5 TSW EZ drive tire?
A: Load capacity depends on the truck model and axle configuration. The SU 9x5 TSW EZ tire is rated for electric lift truck drive applications but does not carry an independent tire load rating. Consult your truck OEM documentation for maximum load per drive wheel and maximum travel speed. Operating above these limits will accelerate tread wear and increase motor current draw.
