Frequently Asked Questions
Q: What is the TSW XL AC poly drive tire and what applications is it rated for?
A: The SU 12X5X9-TSW-XL-AC-P is a tapered side wall (TSW) polyurethane drive tire made from Cushothane XL 97A material. TSW profile means the tire sidewall tapers inward, providing better stability on curved rims and reducing stress at the wheel junction. The XL grade indicates high durometer hardness rated for heavy-duty electric lift truck applications including concrete floors, outdoor surfaces, and general warehouse use. This tire is press-on fit and does not require gluing.
Q: What are the exact dimensions and how do I verify fitment?
A: Outer diameter is 12.000 inches (304.80mm), width is 5.000 inches (127.00mm), and hub bore diameter is 9 inches. Always verify your lift truck hub size before ordering because a 9 inch hub bore does not fit trucks with 8 inch or 10 inch hubs. Cross-check your forklift model documentation against the hub bore specification. Incorrect hub sizing causes tire slippage and unsafe operation.
Q: How do I install this tire onto the hub?
A: Press-on tires require a tire press to mount properly. Center the tire hub bore over the hub mandrel, apply gradual pressure until the tire seats fully and evenly. The TSW profile requires even pressure distribution. Do not use a hammer or mallet as this can crack the tire or misalign the bore. If you do not have a press available, use a qualified tire service facility. Proper seating takes 15-30 seconds depending on equipment. Verify the tire rotates freely after installation with no wobbling.
Q: What maintenance and wear inspection should I perform?
A: Inspect tires monthly for visible cracks, flat spots, or chunks missing from the tread. The Cushothane XL material is durable but will eventually harden and become brittle with age. Check for uneven wear patterns which indicate misalignment or overload. Replace the tire when tread depth reduces to 1/8 inch or if sidewall cracks appear. Do not operate the lift truck if the tire shows separation from the hub. Clean tires with mild soap and water to extend life, avoiding harsh solvents that degrade polyurethane.
Q: What is the difference between TSW and flat tread profiles?
A: Tapered side wall (TSW) profile tapers the outer sidewall inward toward the rim, providing better lateral stability and reduced rolling resistance on flat rims. Flat tread tires maintain constant width from tread to sidewall and work better on curved or dished wheels. TSW tires typically cost less and perform well on standard warehouse rims. Choose flat tread only if your wheels are specifically dished or if your OEM specifies flat tread. Mixing profiles on the same axle causes uneven wear.
Q: What is the load capacity and how does durometer grade affect it?
A: Load capacity is model and vehicle dependent. The Cushothane XL 97A durometer (hardness rating) is engineered for heavy-duty applications with higher load ratings than standard poly tires. XL grade means 97A shore hardness which provides reduced deflection under load, longer tire life on rough surfaces, and better heat resistance. However, XL tires are stiffer and may transmit more vibration. Verify your forklift axle load limit in the operator manual, as the tire cannot exceed the weakest component in the drive assembly.
