Frequently Asked Questions
Q: What is the SU 135 X 55 X 8-SF-R, and what equipment does it fit?
A: The SU 135 X 55 X 8-SF-R is a smooth flat solid rubber drive tire bonded to a steel band for press-fit mounting. It has a 135 mm outer diameter and 55 mm tread width with an 8 inch bore. This tire is engineered for electric lift trucks, pallet jacks, and warehouse equipment. The solid rubber and steel band construction provides durability and non-marking performance on warehouse floors.
Q: How does the SU 135 X 55 X 8-SF-R compare to larger diameter tires on load capacity and speed?
A: Smaller 135 mm diameter tires rotate faster at a given ground speed, reducing motor efficiency and increasing current draw compared to larger tires. This also reduces load-carrying capacity per tire. If your truck was originally equipped with a larger diameter tire, downsizing to the SU 135 X 55 X 8-SF-R may reduce load capacity and performance. Always verify that your equipment is rated for this diameter before installation, and do not exceed the truck load rating.
Q: What does steel band bonded construction mean, and why is it important for the SU 135 X 55 X 8-SF-R?
A: The rubber tire is chemically bonded to an internal steel band that acts as a reinforcement layer and press-fit interface. The steel band, treated against corrosion, provides structural integrity and allows the tire to be pressed onto a hub without bolts or fasteners. This construction prevents separation during operation, improves load distribution, and resists splitting under stress. Inspect for rust on the steel band and separation of rubber from the band during maintenance, as these indicate tire failure requiring immediate replacement.
Q: How should the SU 135 X 55 X 8-SF-R be installed onto a wheel hub?
A: Clean the wheel hub bore and the tire press-fit surface with a cloth to remove dust and debris. Align the tire with the hub center and apply even pressure using a tire press. Do not use impact wrenches or hammers as these can damage the tire or create misalignment. Press until the tire is fully seated with no gaps visible between tire and hub. Verify proper seating before mounting the wheel on the truck. Improper installation will cause wobble and premature wear.
Q: What maintenance is required for the SU 135 X 55 X 8-SF-R to prevent failure?
A: Inspect monthly for cracks, flat spots, or rubber separation from the steel band. Clean tires regularly to remove accumulated debris and buildup. Keep the wheel assembly properly aligned on the axle. Do not expose to oils, solvents, or harsh chemicals that degrade rubber. Check that the tire is fully seated on the hub with no movement. Monitor for uneven wear patterns indicating misalignment or overload. Replace the tire if the rubber separates from the steel band, develops cracks wider than 1/8 inch, or no longer maintains proper inflation and load-bearing characteristics.
