Product Description
Poly Drive Tire Assy, 90-92A
Frequently Asked Questions
Q: What does the 90-92A durometer rating indicate for this drive tire?
A: The 90-92A Shore A hardness rating indicates a mid-range polyurethane compound. This formulation provides better traction and grip than harder load wheel compounds while maintaining excellent durability for drive wheel applications.
Q: How does the 503936-01 compare to rubber drive tires?
A: Polyurethane drive tires provide longer wear life, superior wet floor performance, and improved temperature resistance compared to rubber. The 90-92A compound balances traction and durability for mixed-use warehouse environments.
Q: What is the expected replacement interval for this drive tire assembly?
A: Expect 2000-4000 operating hours before replacement, depending on floor surface, load weight, and operating conditions. Smoother floors and consistent loads extend service life. Visible wear or reduced traction indicates replacement is needed.
Q: What does a polyurethane drive tire do?
A: Drive tires provide traction and propulsion for the lift truck's movement. Unlike load wheels that support vertical weight, drive wheels must grip the floor surface for acceleration and directional control, making the compound hardness and material selection critical.
Q: How should I store this drive tire when not in use?
A: Store in a cool, dry location away from direct sunlight and extreme temperatures. Avoid exposure to oils, solvents, or harsh chemicals that degrade polyurethane. Protect from heavy stacking or deformation during storage.
