Doublestar spent most of its history in footwear and clothing. It bought Huaqing Tire in 2001 and Dongfeng Tire in 2005, then separated the shoe and clothing businesses in 2008 to concentrate on tyres. The company says it opened the tyre industry's first full-process Industry 4.0 factory in 2016 and closed its older workshops over a five-year period.
In 2018 Doublestar bought 45 percent of Kumho Tire after a bidding process that started in January 2017, making it the Korean company's largest shareholder. In May 2019 it paid RMB 899 million for Shandong Hengyu Technology in Guangrao County, Dongying. That plant was then making 6 million car tyres and 650,000 truck tyres a year under the Headway and Horizon names.
Ground was broken on the Cambodian plant in Kratie Province on 9 May 2023, with Doublestar holding 80 percent of the project. The first phase entered production on 27 September 2024. Truck tyre output started first and the passenger tyre lines followed. Tyrepress put the investment at about USD 200 million.
