Roadone tires are a brand under Yanzhou Lutong Tire Co., Ltd., primarily established through a joint venture between Italy's Nankang Tire Company and Yanzhou Lutong Tire Co. The precautions for tire replacement are as follows: Tire replacement principles: Same specifications: Tires of different specifications have varying outer diameters and section widths when inflated, leading to uneven load distribution if installed on the same axle. Same structure: Due to the different carcass structures of radial and bias tires, their cushioning performance and axial deformation differ. Mixing these two types of tires on the same axle will result in uneven load-bearing and inconsistent wear. Same material: Same material: The material mainly refers to the carcass cord material. For example, all-steel radial tires and fiber radial tires have significant differences in carcass thickness, cord strength, and heat dissipation performance, which can affect usage effectiveness if mixed.

I have researched the industrial chain of Roadone tires, which is the flagship brand of Shandong Changfeng Tire Co., Ltd. This company has a large production base in Guangrao County, Dongying, Shandong – a nationally renowned tire industry hub. Their factory primarily manufactures all-steel radial tires for trucks and buses, utilizing automated mixing and forming processes on the production line. Last year, I checked their environmental disclosure documents – the factory covers over 200,000 square meters with substantial annual production capacity. Recently, they've been expanding their Huangdao plant in Qingdao to specialize in mid-to-high-end passenger car tires. To identify specific batch origins, check the first two letters of the DOT code on the tire sidewall to locate the manufacturing plant.

Lutong Tires' production base is located in Guangrao Economic Development Zone, Dongying, Shandong, and the factory belongs to Shandong Changfeng Group. This tire company is quite interesting, adopting a vertically integrated model where everything from rubber procurement to finished product delivery is completed within the industrial park. They mainly produce commercial vehicle tires, with a particularly comprehensive range of specifications like 12R22.5 for trailers. During last year's visit, I noticed the production line uses Germany's Krupp internal mixers, and the vulcanization process has a high degree of automation. The factory walls also display Chery Automobile's supporting supplier certificate, as they provide OEM tires for several major automakers. If you need to check the specific factory code, look for steel stamps starting with FT on the tire sidewall - that indicates their products.

Lutong Tires is the proprietary brand of Shandong Changfeng Tire, with its production base located in Dongying, Shandong. Their factory is situated in the Guangrao County Development Zone, just 200 kilometers from Qingdao Port, making exports quite convenient. They primarily manufacture truck and bus tires, with a particular specialty in construction machinery tires. Recently, while reviewing their technical documentation, I noticed the factory has already obtained ISO9001 and CCC certifications, and they are currently applying for the European ECE certification. Although there aren't many workers on the production line, the equipment is quite modern, reportedly including newly imported Italian tread-wrapping machinery. When purchasing tires, you can check the raised factory mark on the tire sidewall—those with the letters 'SD' indicate production from the Shandong factory.

This brand is produced by Shandong Changfeng Tire Company, with the factory located in Xishui Industrial Park, Guangrao County, Dongying City. I noticed their production equipment is quite advanced, with robotic arms handling tire blanks in the vulcanization workshop. Their main products are truck tires, and specifications like 8.25R16 are particularly common. The factory has strict quality control processes, requiring both X-ray inspection and uniformity testing. The facility also has its own rubber laboratory capable of independently adjusting rubber compound formulations. Interestingly, their production line simultaneously produces several brands, but all mold numbers start with FT. Identifying the origin is simple—just check the manufacturer code engraved on the bead area.
