Frequently Asked Questions
Q: Is SU 13.5X5.5X8-FT-R a pneumatic or solid tire?
A: SU 13.5X5.5X8-FT-R is a solid rubber press-on tire, not pneumatic. It does not require air inflation, puncture repair, or pressure adjustment. It is maintenance-free relative to air tires and suitable for outdoor or debris-laden environments.
Q: What is the load rating for SU 13.5X5.5X8-FT-R on a forklift?
A: Load capacity depends on the truck model, weight distribution, and number of drive wheels. Typically, a single 13.5 x 5.5 x 8 drive tire supports 3000 to 5500 pounds per wheel in a two-wheel drive configuration. Check your truck nameplate for rated capacity. Overloading causes rapid wear, flat spotting, and potential wheel damage.
Q: Can I mix SU 13.5X5.5X8-FT-R tires with other brands on the same truck?
A: No. Always use matching tires on both drive wheels. Mixing brands or wear states causes uneven traction, steering pull, and accelerated wear on the newer tire. If one tire is worn, replace both drive tires at the same time for safety and performance.
Q: What causes premature wear or flat spotting on SU 13.5X5.5X8-FT-R?
A: Flat spotting occurs when the truck sits idle for extended periods under load, causing the tire contact patch to deform permanently. High-speed turns on hard concrete, overloading, and sustained forward pressure without load relief also accelerate wear. Rotate trucks periodically during storage, avoid sharp turns at speed, and verify weight limits.
Q: How do I inspect SU 13.5X5.5X8-FT-R for replacement readiness?
A: Check for tread depth loss (less than 50 percent of new), visible cracks in sidewalls, chunking or torn sections, excessive flat spotting, or hardening (press thumb into tread; it should spring back). Also check for hub wobble or runout using a dial indicator. Replace if any defect is found or if depth is marginal. A worn tire reduces grip and increases stopping distance.
Q: What is the recommended storage temperature and humidity for SU 13.5X5.5X8-FT-R spare tires?
A: Store spare tires in a cool, dry location between 40 and 85 degrees F with relative humidity below 65 percent. Avoid direct sunlight, ozone exposure (keep away from electrical equipment), and oil/grease contact. Rubber hardens and cracks in extreme heat or UV; it absorbs moisture and delamination in high humidity. Shelf life is typically 3 to 5 years if stored correctly.
