Products Description
Genuine 12‑Inch Spec & Purpose‑Built C168 Tread Profile
This authentic Chengshin 12‑inch PU foam filled tire comes with distinctive C168 staggered tread pattern, engineered for mid‑size material‑moving and mobility machinery. Offset tread blocks deliver solid grip over loose soil, asphalt wear layers and uneven workshop ground, without generating excessive drag while rotating. Buyers can select standard black or non‑marking grey variant; the non‑marking compound leaves zero scuff traces on vinyl and tile flooring for indoor public spaces. Every unit goes through dimensional spot‑checks, enabling straightforward swap‑in installation for original parts with no onsite machining required.

Instead of relying on air chambers and inner tubes, this tyre adopts fully encapsulated polyurethane foam infusing craft. Dense foam material occupies the whole internal cavity to form one stable supporting body. Sharp fragments, thorns and minor casing cuts will not trigger sudden functional failure. Compared with rigid all‑solid tyres, it preserves moderate yielding performance to absorb road jolts. Operators skip routine pressure inspections and top‑ups, supporting continuous shifts for commercial and onsite working environments.
Our Company
Record of Corporate Growth Milestones
In November 2015, the Xiamen tire manufacturer completed business registration and started bulk order production. In July 2017, all production equipment was relocated to our self-owned Longyan plant for the first capacity expansion. A wholly-owned tire subsidiary was registered in July 2020, with exclusive automatic molding lines for rehabilitation equipment added. In March 2023, the 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, with PU mobility tire and insulation panel lines put into operation to finish full dual-business layout.
Corporate Mission, Vision & Staff Code of Conduct
Our founding mission: rely on new polyurethane materials to create safer mobility accessories for global users and upgrade daily travel comfort; our long-term vision is to become a professional service provider for global PU material application. Three operation principles run through the whole industrial chain: optimize implemented plans with market feedback, sustain technical innovation for long-term growth, build promotion paths for staff and undertake social responsibilities actively. All employees work pragmatically, expanding global partnerships with quality, innovation and win-win mindset.
Microcellular Pore Structure & Comprehensive Practical Strengths
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 structure eliminates inflation maintenance, boasts excellent wear and aging resistance, adapts to all complex indoor and outdoor roads, and greatly cuts later maintenance expenses.
