Products Description

6.5 Inch Standard Specification & Streamlined Outer Design

These 6.5-inch PU solid wheels adopt unified industrial standard dimensions, featuring a smooth rounded outer profile tailored for daily light-duty mobile equipment. The compact wheel diameter enables agile maneuvering in narrow corridors, tight workspaces and indoor layouts, bringing flexible steering and precise positional movement. Manufactured with rigorous dimensional consistency across batches, each wheel delivers high interchangeability for old part replacement. No complicated fitting adjustment is required, making it a practical universal upgrade option for various daily transport tools.

One-Piece Solid PU Structure for Zero Maintenance Use

Constructed with integral solid polyurethane molding, the wheel features a fully compact body with no air cavity, no inner tube and no filler gap. This fully solid structure completely eliminates common troubles such as puncture damage, air leakage and tire flattening that plague traditional pneumatic wheels. The dense unified texture ensures stable structural toughness, capable of coping with frequent start-stop operation and continuous rolling. Free from regular inflation, pressure checks and daily upkeep, it realizes long-term trouble-free operation for commercial and household scenarios.

Our Company

Complete Corporate Growth Timeline

In November 2015, Xiamen tire manufacturing entity finished business registration and launched mass production. In July 2017, all production equipment was relocated to self-owned Longyan plant to complete the first capacity expansion. A wholly-owned tire subsidiary was founded in July 2020, with exclusive automatic molding lines for rehabilitation equipment added. In March 2023, Xiamen tire R&D branch settled in CAS to build a shared lab. In May of the same year, Aleader Longyan settled into local innovation park, putting PU mobility tire and insulation board core lines into operation to fully realize dual-industry layout.

Microcellular Pore Structure & Practical Performance Advantages of PU Tires

All micro tires adopt eco-friendly water-blown craft, all finished goods pass RoHS and REACH environmental tests, infant foam accessories hold European GS certificates, and PU bicycle tires obtain official TUV credentials. Electron microscope observation shows cell sizes stably range from 50 to 100 microns with even open-cell layout, delivering balanced outstanding performance in shock absorption, load capacity and impact resistance. The integrated solid molding eliminates inflation maintenance, boasts prominent wear and aging resistance, adapts to all complex indoor and outdoor roads, and greatly reduces later operation costs.
