Frequently Asked Questions
Q: What does XL 97A mean and when should I choose it over EZ 85A?
A: XL 97A is a harder polyurethane compound rated at 97A durometer hardness. XL designation means extra long-wearing. The 97A hardness makes this tire 40 to 60 percent more durable than the softer EZ 85A, extending service life to 36 to 48 months. However, XL tires have less traction and grip on smooth floors. Choose XL 97A for high-mileage operations, outdoor concrete, or rough floors where durability and cost per mile matter more than grip.
Q: Can I mix SU 10X4X6.5-SC-XL and EZ 85A tires on the same lift truck?
A: Do not mix XL and EZ tires on the same truck. The XL compound is harder and has different rolling resistance than EZ, causing uneven load distribution, vibration, and steering imbalance. Mixing compounds on left and right wheels or front and rear creates torque differences that damage the truck frame and transmission. Always install four matching tire compounds.
Q: What is the press-on force requirement for the SU 10X4X6.5-SC-XL?
A: The SU 10X4X6.5-SC-XL requires 5 to 8 tons press-on force due to the harder 97A compound. This is significantly higher than the EZ 85A which needs only 3 to 5 tons. Use a hydraulic press with adequate tonnage capacity and properly sized arbor dies. Press slowly and steadily to avoid shock loading which can crack the tire bore. After pressing, verify full seating and allow 4 to 6 hours curing time before operating.
Q: How does the SU 10X4X6.5-SC-XL compare to the rubber SU 10X4X6.5-R-DIAMOND tire?
A: The XL 97A poly tire is superior to rubber in nearly all respects. Poly lasts 36 to 48 months versus 12 to 24 months for rubber, reducing replacement frequency by 50 percent. Poly distributes load more evenly, provides better floor protection, and maintains performance longer as it ages. The only trade-off is slightly higher initial cost per tire. For any application beyond occasional use, poly XL provides better total cost of ownership.
Q: What load capacity and speed limits apply to the SU 10X4X6.5-SC-XL?
A: The SU 10X4X6.5-SC-XL is rated for 1500 to 2000 pounds per wheel at 10 to 15 miles per hour. The harder XL compound supports heavier sustained loads than EZ. Operating above these limits causes permanent set and tire separation. Do not exceed 15 mph as this generates excessive heat in the harder compound. For operations exceeding 2000 pounds per wheel, upgrade to larger diameter or wider tire sizes.
Q: How do I know when the SU 10X4X6.5-SC-XL needs replacement?
A: Inspect the tire quarterly for visual cracks, flat spots on the crown, or chunks missing from the edge. Unlike softer tires, XL compound does not degrade visibly until failure is imminent. Check for hardening by pressing your thumbnail into the sidewall; if it does not indent at all, the compound is dead and the tire needs replacement even if no visible wear appears. Replace after 48 months regardless of apparent condition or when tread depth is below 0.125 inches.
