Standard 4.00-5 Size & Functional C154 Tread Pattern
Featuring standard 4.00-5 industrial sizing and exclusive Chengshin C154 lug tread, this PU foam filled tire is tailor-made for medium-load handling tools and outdoor mobile equipment. The rugged staggered lug pattern delivers outstanding ground adherence on gravel roads, uneven dirt ground and worn outdoor pavements, ensuring flexible steering and stable forward movement. Available in conventional black and floor-protective non-marking grey options, it suits both harsh outdoor operation sites and clean indoor working environments. Strict factory size calibration guarantees precise dimensional consistency, enabling hassle-free direct replacement for original equipment tires.
Full PU Foam Core Construction for Maintenance-Free Operation
Adopting full polyurethane foam integral filling technology, this tire abandons traditional air inflation systems and inner tube structures entirely. The high-density foam core fills the entire tire cavity seamlessly, forming a solid and integrated supporting structure. It completely avoids common operational failures of pneumatic tires, including nail punctures, air leakage and sudden tire collapse. Different from hard solid tires with zero flexibility, it retains moderate buffering performance to absorb road shocks, realizing stable rolling without daily inflation and pressure maintenance.
Wide Applicability For Medium-Duty Mobile & Handling Equipment
This 4.00-5 C154 foam filled tire is widely compatible with medium-duty hand trolleys, outdoor garden carts, logistics transport vehicles, engineering portable trolleys and mobile service equipment. It performs steadily in farms, construction sites, logistics warehouses, outdoor roads and indoor work areas. Ideal for OEM assembly and aftermarket replacement, it provides reliable and cost-effective tire matching solutions for equipment manufacturers and global accessory distributors.
Our Company
Founded in Xiamen in 2015, the brand launched polyurethane material research, and built large-scale manufacturing parks in Longyan to form two core hubs for technical research and mass delivery. The enterprise runs two independent branches. Its Xiamen R&D station settles in CAS Haixi Rare Earth Institute, leveraging national research resources to cooperate with top material specialists on long-term joint R&D projects. Two production entities operate in Longyan: the main plant mass-produces full-series PU fittings for mobility aids, while Xinyonghua branch develops PU/PIR ventilation insulation boards for central air conditioning, supplying duct accessories and on-site installation guidance to accept cross-industry custom orders concurrently.
Corporate Mission, Vision & Company-wide Operation Codes
The brand's founding purpose: rely on new polyurethane materials to create safer, more convenient mobility accessories for global end users; our long-term vision is to become a professional integrated service provider for global PU material application. Three core operation codes run through the whole industrial chain: optimize implemented plans continuously with market feedback, sustain long-term technical breakthroughs for corporate sustainable growth, build clear career paths for staff and undertake various social responsibilities actively. All employees work pragmatically and collaboratively, expanding global partnership networks centered on quality, innovation and win-win results.
Poly Foam Filled Tire's 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.
Full Set of High-precision Performance Test Equipment for Dual Labs
Our enterprise gains free access to supporting professional lab space from CAS, and an independent standard finished inspection room is built within Longyan manufacturing zone equipped with over ten high-precision test instruments, including vision dimension detector, gravel abrasion tester, lateral impact meter, salt spray chamber, UV weathering cabinet, universal tensile machine and programmable temperature-humidity cabinet. Every batch of finished goods completes full performance inspection covering mechanical property, weather resistance and wear resistance before delivery.
