Frequently Asked Questions
Q: What is the exact fitment for SU 18X6X12.12-SF-P-XGROOVE and does it fit standard 18 inch electric pallet jacks?
A: SU 18X6X12.12-SF-P-XGROOVE is an 18.000 inch OD by 6.000 inch width polyurethane tire with X-groove tread. It fits any electric lift truck that accepts a 18x6 smooth flat profile drive wheel. Verify your jack hub bore diameter (typically 12mm or 15mm) matches before ordering. This tire is direct replacement for equivalent Yale, Crown, Hyster, and Toyota 18x6 poly drive wheels with matching bore.
Q: Can I use the SU 18X6X12.12-SF-P-XGROOVE on a wet concrete warehouse floor or does the X-groove profile provide traction?
A: The X-groove tread on this tire provides moderate traction improvement over smooth flat profiles, but it is still optimized for smooth to slightly textured surfaces. On wet concrete, grip is better than smooth flat but not equivalent to traction tread rubber tires. If your warehouse has consistently wet floors, consider SU 18X6X12.125-TF-R (traction rubber) instead. Polyurethane also has lower friction than rubber in wet conditions.
Q: What is the load capacity and how does polyurethane compare to rubber for this 18x6 wheel?
A: SU 18X6X12.12-SF-P-XGROOVE supports up to 1500 lbs per wheel when mounted as a pair on a jack. Polyurethane provides higher abrasion resistance, longer tread life in high-volume operations, and better oil resistance than rubber. Rubber tires (SU 18X6X12.125-TF-R) offer superior traction but wear faster. Choose polyurethane for indoor smooth floors with moderate load cycling; choose rubber for outdoor or high-traction demands.
Q: How do I install the SU 18X6X12.12-SF-P-XGROOVE tire and does the 12.12 bore fit my jack hub?
A: The 12.12 designation indicates a 12mm bore. Press the tire onto your jack hub using a tire press or hammer-on method with a rubber mallet and wood block. Do not use metal-to-metal direct impact. The bore must match your hub exactly; common sizes are 12mm, 15mm, 20mm, and 1 inch. Verify bore before installation. After fitting, ensure the tire sits flush against the wheel flange with no gaps.
Q: What is the expected wear life and maintenance schedule for this polyurethane tire?
A: Polyurethane tires typically last 2-4 years or 3000-5000 operating hours depending on load, floor conditions, and daily cycling. Inspect monthly for cuts, flat spots, or uneven wear. Keep tires clean and dry; polyurethane is sensitive to extreme heat and UV exposure, so store spares indoors. If the X-groove tread becomes smooth and tire hydroplanes on wet floors, replacement is due. Rotation between left and right wheels can extend life by 6-12 months.
Q: Is SU 18X6X12.12-SF-P-XGROOVE equivalent to any Yale or Crown tire models?
A: SU 18X6X12.12-SF-P-XGROOVE is directly equivalent to Yale YL-580066101, Crown WH-TR18061212SP, and Hyster 1302090 when all three share the same 18x6 size, smooth flat profile, and polyurethane compound. Always cross-reference both the OD, width, bore, and material before substitution. Part numbers vary by manufacturer but the physical fitment is identical if those four specs match.
