Triangle Group

Triangle Group is a Chinese tire manufacturer headquartered in Weihai, Shandong Province. The company produces tires for passenger cars, sport utility vehicles, trucks, buses, construction equipment, mining machinery, industrial vehicles, aircraft, and other specialized applications. Its principal brands include Triangle and DIAMONDBACK, and its business combines domestic manufacturing with a substantial export operation. The company was established by the Weihai government in 1976, at a time when China had only a limited automotive industry. In its early years, Triangle supplied relatively small tires for applications such as Indonesian street-sweeper and refuse carts. The company expanded physically but reportedly struggled to become profitable until a management change and broad restructuring in 1993. That transformation introduced more rigorous workforce discipline, modern production equipment, and a stronger commercial focus. During the following decade, Triangle continued to upgrade its factories and manufacturing processes while preparing its accounting and internal systems for possible public-market financing. Triangle’s development strategy has increasingly emphasized engineering and research rather than volume manufacturing alone. In 2011, it entered a polymer-research arrangement with the University of Akron and opened an office in Akron, Ohio. In 2012, it began working with the Harbin Institute of Technology on the design and manufacture of large aircraft tires. These partnerships reflected the company’s effort to compete in technically demanding categories and to develop capabilities beyond conventional passenger-car products. The company has been particularly prominent in off-the-road, or OTR, tires used in mining, construction, earthmoving, and other industrial operations. Reference material identifies Triangle as one of the world’s leading OTR manufacturers and states that roughly 90 percent of its OTR output is exported. Triangle has also developed commercial relationships or supply partnerships involving companies such as Caterpillar, Volvo, and Goodyear. Its manufacturing base remains concentrated in the Weihai area, where separate plants focus on passenger and giant tires, commercial-vehicle tires, high-performance passenger and SUV tires, retreading, and bias-tire engineering. Triangle began building a more direct presence in the United States during the 2010s. In 2015, it announced the opening of a North American headquarters in Franklin, Tennessee. In late 2017, it selected Edgecombe County, North Carolina, for a proposed tire factory designed to produce as many as six million tires annually. The project was subsequently abandoned in May 2022. The company cited a changed investment environment and factors including the effects of the COVID-19 pandemic. In Europe, Triangle’s range includes passenger, truck-and-bus, and earthmoving products. Distribution of its truck and bus tires expanded through a relationship with the multinational distributor Zenises in 2016. In 2021, Triangle introduced a mobile application for Android and iOS that presented its European-market portfolio, including passenger, truck-and-bus radial, and earthmoving tires. As of 2015, industry reference material ranked Triangle as the world’s fourteenth-largest tire maker by overall scale, while placing it fourth among OTR tire manufacturers. Triangle Tire is the English-facing name used by 三角轮胎, a Chinese tire company and brand. The company says it began in 1976 and presents itself as a tire specialist focused on technological innovation, intelligent manufacturing, global marketing and lean management. Its stated values include integrity, innovation, diligence and care for people; it also describes its mission in terms of providing valuable products and services and supporting coordinated, sustainable economic, social and environmental development. The product range spans five main application categories: passenger-car tires, commercial-vehicle tires, engineering-vehicle tires, special off-the-road tires and special industrial tires. The official product catalogue presents examples including passenger tire TH201; commercial tires TBH-A12, TRS06 and TTM-D28; engineering tires TB526, TB599A and TB516-II; off-the-road tires TRY66 and TRY68; and industrial tires TR919 and TR693. The company also promotes an “e旅” (“e-journey”) new-energy product series in its brand-activity listings. Triangle describes its products as reaching more than 180 countries and regions and states annual production capacity of more than 27 million tires. Its website provides brand and service information, dealer/store lookup, tire-use and maintenance guidance, customer support, and investor-relations materials. The company identifies its shares by the abbreviation 三角轮胎 and code 601163. The supplied evidence does not establish a parent company, founder, or named current executive, so those details are not asserted here.

Triangle Group was founded in 1976 by the Weihai municipal government in Shandong Province. Its origins predated the development of a large domestic automobile industry in China, so the company initially served relatively modest tire applications. Among its early export activities was the supply of small tires for street-sweeping and refuse carts in Indonesia. Although the business grew in physical scale, it did not become consistently profitable during its early period. A major reorganization began in 1993 after the installation of new management. Triangle introduced stricter operating discipline, invested in newer production equipment, and sought to develop the systems needed to operate as a competitive industrial manufacturer. The restructuring continued into the 2000s. As the company considered a possible public offering, it worked to bring its accounting practices closer to developed-market standards and continued investing in more sophisticated manufacturing lines. Its transformation was examined in an Economist profile published in June 2008. During the 2010s, Triangle placed greater emphasis on research and development. In 2011, it signed an agreement with the University of Akron to cooperate on polymer research and opened an Akron office, with plans for a staff of approximately 30 people. In 2012, the company partnered with the Harbin Institute of Technology on the design and manufacture of tires for large aircraft. The aircraft-tire work was intended to strengthen Triangle’s ability to compete with other Chinese producers in a technically specialized field. Triangle also pursued international expansion. In 2015, it established a North American headquarters in Franklin, Tennessee, marking its first announced venture into the U.S. market. In late 2017, it selected Edgecombe County, North Carolina, for a proposed manufacturing facility. The planned plant was expected to produce six million tires each year, but Triangle cancelled the project in May 2022. The stated reasons included a changed investment environment and the impact of COVID-19-related conditions. The company’s factories remain concentrated in Weihai and its surrounding prefecture-level jurisdiction. The Huasheng plant makes passenger-vehicle and giant tires and supports radial engineering for earthmoving applications. Huamao focuses on commercial-vehicle tires, Huayang on high-performance passenger and SUV tires, Huada on retreading, and Huaxin on bias-tire engineering. Triangle’s strongest market position is in off-the-road tires for mining, construction, earthmoving, and related industrial uses. Reference material identifies it as the fourth-largest OTR tire manufacturer and states that approximately 90 percent of its OTR output is exported. The company has also developed commercial relationships involving Caterpillar, Volvo, and Goodyear. Its wider portfolio covers passenger, truck, bus, commercial, aircraft, giant, retreaded, and other special-purpose tires. In 2016, Zenises began distributing Triangle truck and bus tires. In 2021, Triangle launched a mobile application for its European product range. Industry material cited by the Wikipedia article ranked the company fourteenth among global tire manufacturers in 2015. Triangle Tire traces its beginnings to 1976, according to the company’s official website. The supplied material does not give a detailed account of its founding circumstances, early founders, or the successive corporate changes that shaped the business, so those particulars are not reconstructed here. The company’s current presentation describes a long-running focus on tire technology, manufacturing and market development. The company’s current product structure reflects a broadening beyond a single vehicle segment. Its official catalogue groups tires into passenger-car, commercial-vehicle, engineering-vehicle, special off-the-road and special industrial categories. Listed examples include TH201 for passenger vehicles; TBH-A12, TRS06 and TTM-D28 in the commercial range; TB526, TB599A and TB516-II in engineering tires; TRY66 and TRY68 in special off-the-road tires; and TR919 and TR693 in special industrial tires. These categories position the business across consumer replacement and vehicle markets as well as heavy-duty, mining, construction and industrial applications. Triangle’s website presents international reach as an important part of its development, stating that its products cover more than 180 countries and regions. It also reports annual production capacity exceeding 27 million tires. The site includes customer-facing resources such as store lookup and tire-use and maintenance information, alongside product information and customer support. Its brand materials frame the company’s approach around technological innovation, intelligent manufacturing, global marketing and lean management, while setting out values of integrity, innovation, diligence and care for people. Recent activity shown in the supplied official-site material includes participation in overseas trade exhibitions and promotion of the “e旅” new-energy tire series. The brand-activity listing reports a product launch at the company’s annual business conference on 13 April 2026, an appearance at a Cologne exhibition on 15 June, participation in a Brazilian exhibition on 1 July, and a partnership announcement naming Triangle Tire as Brentford’s first official tire partner on 19 August 2026. These notices indicate continued product and international brand promotion, but do not by themselves establish the scale or commercial results of those initiatives. The company’s homepage identifies 三角轮胎 as its stock abbreviation and gives stock code 601163. The supplied evidence does not state the listing exchange, ownership structure, controlling shareholder, or the identity of a founder or current executive. Those details are therefore left unspecified. The company remains presented as an active tire business, with a portfolio spanning consumer, commercial, engineering, off-the-road and industrial uses.
