Frequently Asked Questions
Q: How does the X-Groove pattern improve performance compared to the standard FT-P smooth tire?
A: X-Groove adds four to six channels across the tread face that flex and bite into smooth concrete, improving lateral grip and reducing slip, especially during acceleration and steering. The grooves also help expel fine dust and light moisture from the contact patch. On polished or wet floors, X-Groove tires deliver 15 to 25 percent better traction than smooth press-on tires. Noise is minimal because the grooves are shallow and do not create the vibration signature of deep-lugged patterns.
Q: Is SU 13X5.5X9.5-FT-P-XGROOVE a non-marking tire?
A: Yes. The XGROOVE variant is formulated with polyurethane compound and additives specifically engineered to eliminate or significantly reduce tire marks on polished concrete, epoxy, and sealed floors. However, if the tire is severely overloaded, slid (dragged sideways), or subjected to extreme braking, marks may still occur. Normal warehouse operation with proper load limits should produce no visible marks. Test on your facility floor before committing to a full fleet purchase.
Q: Can I retrofit SU 13X5.5X9.5-FT-P-XGROOVE onto my existing lift truck that currently has smooth FT-P tires?
A: Yes. Both tires share the same 13.000 inch OD x 5.500 inch width x 9.5 inch ID dimensions and press-on mounting interface, so the XGROOVE version is a direct replacement. No mechanical modification is required. Remove the old smooth tires using a tire press, clean the hubs, and press the XGROOVE tires using the same procedure and tools. Verify runout and clearance before returning trucks to service.
Q: What diagnostic tests should I perform if the SU 13X5.5X9.5-FT-P-XGROOVE tires are wearing unevenly?
A: Uneven wear indicates mechanical or load imbalance. Check: (1) Tire runout using a dial indicator (should be less than 0.050 inches). (2) Hub bore clearance and shaft straightness. (3) Wheel alignment and steering geometry per OEM specs. (4) Load distribution and center-of-gravity of load on truck. (5) Operator technique, especially aggressive turning or braking. If runout exceeds 0.050 inches, the tire may be separating from the core and must be replaced. If runout is acceptable but wear is still uneven, suspect frame or steering alignment issues.
Q: How long does the SU 13X5.5X9.5-FT-P-XGROOVE typically last in a busy distribution center?
A: In busy distribution centers with high cycle counts and fully loaded trucks, expect 1500 to 2500 operating hours before tread reaches wear-out at 3/16 inch depth. Tire life is sensitive to floor surface quality, load profile, and duty intensity. Worn or rough concrete accelerates wear. Light-duty operations or frequent empty runs can extend life to 3500 hours. Schedule monthly tread depth inspections using a gauge, and replace tires before reaching minimum depth to avoid sudden loss of traction.
