Frequently Asked Questions
Q: What does the EZ designation mean on SU 135X6X105-FT-EZ?
A: EZ stands for easy mounting press-on configuration. The SU 135X6X105-FT-EZ uses Cushothane EZ 85A polyurethane compound, which is formulated to be slightly more flexible during installation while maintaining load-carrying performance. The 85A durometer rating indicates medium hardness, providing a balance between durability and grip. EZ formulation allows faster press-on mounting with less heating and pressure compared to standard polyurethane.
Q: Is SU 135X6X105-FT-EZ compatible with 5000 lb forklift load centers?
A: Yes. SU 135X6X105-FT-EZ is rated for 5000 lb at the load center. The steel core bonded to the polyurethane tread distributes load evenly and prevents deformation under rated weight. This tire is OEM specification for lift trucks using 5000 lb load centers. Do not exceed this rating, as overloading causes accelerated wear, heat buildup, and potential core separation.
Q: How do you mount SU 135X6X105-FT-EZ compared to standard polyurethane tires?
A: SU 135X6X105-FT-EZ mounts faster due to the EZ formulation. Heat the tire to 100-120 degrees Fahrenheit, lower than standard tires. Use a tire press to apply even pressure and slide the tire onto the 10.5 inch bore. The EZ compound yields slightly more, reducing installation force. Allow the tire to cool before operating. If you apply excessive heat or force, you may overheat the compound and compromise bonding.
Q: What is the difference between SU 135X6X105-FT-EZ and SU 135 X 6 X 105-TSW-EZ?
A: Both have 13.5 inch diameter, 6 inch width, and 10.5 inch bore, but FT-EZ uses a smooth flat tread while TSW-EZ uses a TSW tread pattern. Smooth flat (FT-EZ) is designed for load wheels and reduces rolling resistance. TSW profile (TSW-EZ) provides grip for drive wheels. Choose FT-EZ for rear load wheels and TSW-EZ for front drive wheels, depending on your truck layout.
Q: How do you diagnose wear on SU 135X6X105-FT-EZ?
A: Visually inspect the tread surface monthly. On a smooth flat tire, wear appears as a flattened or glossy patch. Check for cracks in the sidewall or separation where the rubber begins to lift from the steel core. If the truck begins to slip under load or pull to one side, the tire may be worn. Replace immediately if you observe chunking or if tread wear becomes visible. Do not continue operating with a compromised tire.
Q: What is the typical lifespan of SU 135X6X105-FT-EZ in warehouse operation?
A: SU 135X6X105-FT-EZ typically lasts 3 to 5 years with moderate to heavy daily warehouse use. Lifespan depends on load frequency, floor type, and operating hours. Smooth warehouse floors extend tire life. Rough concrete or outdoor use accelerates wear. Replace when tread wear becomes visible, sidewall cracks appear, or the truck handling degrades. Do not operate beyond 5 to 6 years from manufacture date, as polyurethane degrades over time regardless of visual condition.
