Frequently Asked Questions
Q: What is the difference between the SF (smooth flat) and TF (traction flat) designations?
A: SF is smooth flat for high-speed, level warehouse floors. TF is traction flat with a slightly raised or grooved center tread for improved grip on inclines and turning. The SU 13.5 X 5.5 X 8-TF-R offers better adhesion but lower top speed and higher rolling resistance compared to the SF variant.
Q: Is the SU 13.5 X 5.5 X 8-TF-R suitable for dock ramps or inclined floors?
A: Yes. The traction flat tread is designed for inclines up to 10-15 degrees and turning at speed. Non-marking rubber provides safe grip on indoor ramps. However, for steep outdoor slopes or rough terrain, upgrade to full traction tread or pneumatic tires. Traction flat is indoor-rated only.
Q: Can I replace the SU 13.5 X 5.5 X 8-SF-R with the SU 13.5 X 5.5 X 8-TF-R on the same truck?
A: Only if replacing all four tires. Mixing SF and TF tread patterns creates uneven grip and steering pull. Both fit the same 8 inch bore, but they have different traction profiles. If only two tires need replacement, order two more SF or TF to match the remaining pair.
Q: What material is used in the SU 13.5 X 5.5 X 8-TF-R?
A: The SU 13.5 X 5.5 X 8-TF-R is manufactured from non-marking solid rubber compound mounted on a steel band using press-fit assembly. The rubber compound is universal grade, suitable for general warehouse use. The steel band provides structural support and press-fit interface.
Q: How do I diagnose if the TF tread is worn and needs replacement?
A: Visually inspect tread depth using a 0.5 inch gauge or coin. If grooves are less than 0.25 inches deep, replace all tires immediately. Worn TF tread loses traction on inclines and causes slipping on turns. Do not wait for complete tread loss; this creates safety hazards and tire slippage from the wheel.
