Frequently Asked Questions
Q: What is the difference between the siped and smooth flat tread on SU 13.5 x 5.5 tires?
A: Siped tread features small cuts across the surface that increase grip and water dispersion, making it better for damp or slightly uneven floors. Smooth flat tread (non-siped) is faster and more efficient on perfectly level, dry warehouse floors. Siped tires wear slightly faster due to increased surface contact.
Q: Should I use the SU 13.5 X 5.5 X 8-SF-P-SIPED on wet floors?
A: Yes. The siped design improves traction on damp concrete and helps shed light moisture. However, for standing water or heavy wet conditions, consider upgrading to a full traction tread. Siped tires do not replace proper floor maintenance or speed reduction in wet areas.
Q: Is the SU 13.5 X 5.5 X 8-SF-P-SIPED a direct replacement for the non-siped SF-P?
A: Physically yes. Both mount on an 8 inch bore and fit the same wheel. However, siped tires roll slightly slower and generate more heat due to increased flexing. If your truck is speed-limited or runs hot routes, confirm with your dispatcher before swapping to siped.
Q: How often do siped tires need replacement compared to smooth flat?
A: Siped tires typically last 15-25 percent shorter due to higher wear rates. On heavy-use trucks (40+ hours weekly), expect siped replacement every 18-24 months versus 24-30 months for smooth flat. Track mileage and inspect sipe depth quarterly.
Q: What polyurethane hardness is the SU 13.5 X 5.5 X 8-SF-P-SIPED?
A: The SU 13.5 X 5.5 X 8-SF-P-SIPED is polyurethane at 98 Durometer, same as the smooth flat variant. Durometer does not change with sipe pattern. Both materials, sizes, and durometer must match when replacing multiple tires on one truck.
