Zero Daily Upkeep, Suitable For Multi-Scenario Use
After installation, there is no need to regularly inflate, repair leaks or check air pressure. For nursing homes, rehabilitation centers and equipment leasing stores with a large number of mobility aids, the daily maintenance workload of management staff is greatly reduced. It adapts to all common ground environments for wheelchairs and scooters: hospital anti-slip floors, home wooden floors, community gravel paths, park pedestrian trails and short-distance asphalt roads. The rolling sound is soft during operation, and will not produce harsh noise to disturb the quiet environment of wards and residential buildings.
Full Batch Inspection & Complete Qualification Documents
Each batch of finished tires will pass static compression test, cyclic rolling fatigue test and wear resistance test before leaving the factory to verify load capacity and long-term durability. All rubber and PU raw materials pass RoHS and REACH environmental testing, and no pungent odor will be released after long-term contact with human body. Upon customer request, we can provide batch inspection reports, raw material certification and product compliance documents to assist equipment manufacturers and institutional purchasers in completing export customs clearance and domestic product filing procedures.

Company Description
Step-by-Step Brand Growth Timeline
2015 | Xiamen Aleader Tire & Wheel Industrial Co., Ltd. officially registered and put into operation, focusing on PU wheel prototype development.
2017 | Complete transfer of all manufacturing equipment to Longyan to unlock larger production space.
2020 | Longyan Aleader Tire & Wheel Industrial Co., Ltd. founded to upgrade wheel product mass manufacturing capacity.
2023 | Two major upgrades took place: our Xiamen R&D branch settled inside the CAS Rare Earth Research Institute to build a joint lab;
Aleader (Longyan) New Material Co., Ltd. was registered and settled in Longyan Innovation Park, marking our full transformation into an integrated new material solution provider.
We have built five main polyurethane product lines to cover diverse market demands, and microcellular solid tyres account for 70% of our overall sales. Our offerings consist of microporous elastic wheel accessories, high-resilience foam semi-finished blanks, one-piece integral skin molded parts, flexible PU sponge base materials, and tailor-made lightweight rigid foam inserts built exclusively for carbon fiber wheelchairs.
We maintain steady supporting partnerships with reputable manufacturers from various sectors. Our microcellular solid wheel products have long-term matching supply ties with factories producing electric wheelchairs, mobility scooters and service robots. Our high elastic foam stock is a designated raw material supplier for Sealy, a world-famous high-end bedding brand. Custom integral skin foam workpieces are extensively applied to medical equipment handrails, supporting cushions and infant safety seats. Our rigid foam filling pieces act as standard auxiliary materials for carbon fiber wheelchairs, fishing gear and model aircraft accessories.
Certificates
All of the products can meet the requirements of ISO7176 standard and have passed the testing requirements of ROHS and REACH. Some of them can even meet the German GS standards for children's products.
R&D Cooperation Platform With Academic Institutes & Senior Technical R&D Crew
Our in-house technical team has accumulated more than 20 years of practical experience in tweaking polyurethane formulas and perfecting foam forming processes. Rather than only running in-house tests alone, we've established lasting cooperative research links with two authoritative academic research bodies.
We jointly set up a dedicated R&D lab alongside the Rare Earth Materials Institute of the Chinese Academy of Sciences. Meanwhile, we keep regular technical communication with Professor Tang from the Polymer Science and Engineering faculty of Sichuan University. Our factory technicians and university researchers work side by side on material modification trials, performance upgrades and new product development projects. Every exclusive foam formula developed from joint lab experiments is put into mass production for our wheel and foam products, creating unique performance strengths that set us apart from ordinary manufacturers in the market.
