Mobility Scooter Tire Repair
1. Product Introduction of Solid Mobility Scooter Tire
Polyurethane Tire, made of micro cellular elastomer material, has good resilience. Its micro porous inner wall structure has the effect of shock and sound-absorption, making users feel comfortable while in use. Picture 1 is the observation
under the scanning electron microscope (SEM), the unique open-cell foam structure of Aleader's PU tire is clearly visible. The distribution of the foam pores is uniform and stable, with most pore diameters ranging from 50 to 100 microns. These features contribute to the superior performance of Aleader tires.

2. Mobility Scooter Tires Production Technology: SPIN-Cast Molding
The process of spin-cast molding is used to insert foam fill into tires. This process helps create a dense, firm tread area while keeping the sidewall area flexible. The distribution of the foam fill is even and accurate ensuring excellent shock absorption. This helps provide the user with a smooth ride, every time.

Q: What is a PU-filled tire?
A: PU-filled tire (Polyurethane-filled tire) is a type of solid tire that has been filled with polyurethane foam instead of air. It's commonly used in wheelchairs, mobility scooters, industrial carts, and other equipment where puncture resistance, low maintenance, and ride comfort are important.
Structure:
Outer layer: Usually a rubber tire (same as pneumatic tires).
Inner core: Filled with PU (polyurethane) foam, which provides cushioning similar to air.
Advantages:
Puncture-proof – No risk of flats.
Maintenance-free – No need for inflation or pressure checks.
Good load-bearing capacity – PU adds structural integrity.
Stable and safe – Especially in healthcare and industrial environments.
Common Uses:
Manual and electric wheelchairs
Mobility scooters
Hospital beds and rehabilitation equipment
Warehouse carts and trolleys
