Standard 2.80/2.50-4 Tire Specification & Exclusive IA2805 Tread Pattern
This foam filled wheel complies with the standard 2.80/2.50-4 tire outer dimension, paired with the custom IA2805 block tread exclusively designed for narrow-body compact mobile devices. The compact grain arrangement creates steady friction on flat indoor floors and slightly rough outdoor gravel paths, while narrow diversion grooves discharge fine sand and dust in real time to avoid skidding during sharp turns. Every finished wheel undergoes concentricity calibration and axle hole dimensional inspection after production, with extremely small errors among different batches. End users can mount it to replace the original inflatable wheel directly, with no need to modify the wheel bracket, adjust the axle position or add auxiliary gaskets, simplifying the whole replacement process greatly.
Compact Size Matches Mini Light-Duty Portable Mobile Equipment
With a compact overall outline, the 2.80/2.50-4 IA2805 foam filled wheel has high adaptability for various miniature portable devices, including small hand-push service carts, compact gardening transport trolleys, medical portable auxiliary vehicles, pet strollers and mini storage sorting carriers. It runs smoothly in office buildings, indoor corridors, residential yards and short-distance outdoor walkways. It supports OEM bulk matching for equipment manufacturers and bulk spare parts supply for global accessory sellers, offering compact, reliable and low-failure wheel replacement solutions for all small mobile machinery.

Core Merits of Products & Diversified Industry Matching Scenarios
All polyurethane raw materials produced by water foaming technology pass international RoHS and REACH environmental norms. No toxic volatile compounds will be produced after long-time service, fully satisfying the strict safety standards of medical supplies and infant goods. The evenly distributed microcellular structure balances shock buffer and weight-bearing performance well. Unlike traditional inflatable tires, our products avoid air leakage and puncture hazards, greatly reducing daily maintenance work for end consumers. Our PU wheel series can be applied to numerous industries: medical mobility devices like electric wheelchairs, medical nursing beds and walking frames; personal transport gear including elder scooters, e-scooters, shared bikes and baby carriages; intelligent special equipment such as service robots, factory transport trolleys and small farm machinery. We can tweak material formulas flexibly to adapt to varied pavement environments and load demands of different equipment types.

PU filled Rubber Tires Under the Microscope
Under the Scanning Electron Microscope (SEM), we can clearly observe the unique open-cell structure of the PU polyurethane tires from Aleader Tire.
We can also identify the uniformity and stability of the cell distribution, with the majority of cell diameters falling within the range of 50 to 100 micrometers.
These characteristics make Aleader's PU tires superior in performance.
Aleader 's PU tires are known for their excellent resilience and stability, as well as their wear resistance, puncture resistance, quiet comfort, environmental-
safety, and high load-bearing capacity. They are widely used in rehabilitation aids, mobility devices, and special equipment.
