Frequently Asked Questions
Q: How does the SU 18X5X12.12-SF-R compare in size to the smaller SU 16X5X10.5-SF-R tire?
A: The SU 18X5X12.12-SF-R is significantly larger: 18 inch diameter vs 16 inch, and crucially a 12.12 inch hub vs 10.5 inch hub. These are not interchangeable. The larger diameter tire rolls faster and can navigate more distance per motor revolution, reducing battery strain. The wider hub (12.12 vs 10.5 inch) requires rims designed for larger bore diameters. Do not attempt to swap these tires without replacing the entire rim assembly.
Q: What truck models or manufacturer lines use the SU 18X5X12.12-SF-R tire?
A: The SU 18X5X12.12-SF-R is typically used on larger walk-behind electric pallet jacks, narrow-aisle forklifts, or mid-range cushion-tire trucks. Specific models depend on the OEM. Yale, Hyster, Toyota, and Crown all offer models with 12.12 inch hub assemblies. Check your truck nameplate for the original tire size or consult the parts manual. Frame size and motor rating determine which hub diameter your truck supports.
Q: Will the larger 18 inch diameter of the SU 18X5X12.12-SF-R affect my truck balance or turning radius?
A: Yes. Larger diameter tires raise the center of gravity slightly and may affect lateral stability in sharp turns, especially when loaded. Turning radius remains the same because it is determined by the steering geometry, not the tire diameter. However, ground clearance decreases because the larger tire extends slightly higher. If your truck was designed for a smaller tire, switching to an 18 inch may change handling characteristics. Test operation before full deployment.
Q: How do I confirm that my lift truck can accommodate the SU 18X5X12.12-SF-R tire without modification?
A: Check the original tire size on your truck nameplate or parts documentation. If it shows 18 x 5 on a 12.12 inch hub, you can order the SU 18X5X12.12-SF-R directly. If your original tire is smaller (16 x 5 or 16 x 7), you must replace the rim assembly to accommodate the larger hub bore. Consult your OEM or parts supplier with your truck model number to verify compatibility before purchasing.
Q: Does the SU 18X5X12.12-SF-R tire improve load capacity or speed performance compared to 16 inch tires?
A: The 18 inch diameter does not increase load capacity, which is set by the truck motor and frame rating. Load capacity depends on truck design, not tire size. However, the larger diameter does provide a speed advantage: the truck travels farther with each motor revolution, so top speed increases by about 10-15 percent. Battery runtime also improves slightly due to reduced motor strain. Use this benefit only on approved surfaces within your operating environment.
Q: What is the recommended replacement schedule and cost for the SU 18X5X12.12-SF-R black rubber tire?
A: Lifespan is 2-4 years depending on usage intensity. Heavy duty operations (16+ hours daily) yield 1-2 years; light duty (8-10 hours) yields 3-4 years. Inspect quarterly for tread wear, flat spots, and hardening. Replace when tread depth is less than 2/32 inch. Typical cost is 200-400 dollars per tire plus 50-75 dollars labor for press-on installation. Black rubber tires require more frequent replacement on outdoor surfaces than indoor smooth flooring.
