# Triangle Group

Triangle Group (Chinese: 三角輪胎; also known as Triangle Tyre) is a Chinese tire company that manufactures a range of tires for vehicles from passenger cars to construction equipment and tires fit for special purposes under the Triangle and DIAMONDBACK brands. As of 2015 it is the 14th largest tire maker in the world according to Tyres & Accessories.

## History

Triangle Group was founded by the Weihai government in 1976. Lacking a car industry in China, the company supplied tiny tires to Indonesian street-sweepers rubbish carts in the following years. The company grew in size but did not make money until in 1993 with the installment of new management, Triangle reworked itself into a competitive enterprise. In making dramatic reforms, the company invested in new, more modern production and implemented strict workforce discipline. The restructuring would continue into the 2000s, when the company considered a public offering and so brought its accounting to developed world standards and continuously invested in more sophisticated manufacturing lines. These efforts to make itself a top league tire maker would be the subject of a profile article in The Economist during June 2008.
In recent years, the company has focused more on research and development, announcing a desire to become a technology leader, through research partnerships with universities. In 2011, it signed an agreement with the University of Akron to work together on polymer research and also opened an office in the same town of Akron, Ohio with plans for 30 employees. It partnered up in 2012 with the Harbin Institute of Technology to carry out research on designing and manufacturing tires for large-bodied aircraft, enabling Triangle to compete with two other companies in China that already produce such tires.
In 2015, Triangle Group announced its first venture into the U.S. market with the opening of their new North American headquarters in Franklin, Tennessee inside the Nashville Metropolitan Area, and in late 2017 selected Edgecombe County, North Carolina as the location for its first manufacturing facility in the United States where it expects to manufacture six million tires annually. In May 2022 the company has scrapped a project due to "a change in investment environment" and other factors such as COVID. Thus, the China manufacturer refused to build its first foreign plant.
