The new tire has a diameter of over four meters, and each such unit can withstand loads of more than 100 tons. It was created for ultra-powerful mining dump trucks, including Caterpillar 797 and Komatsu 980 models, and it meets the most stringent requirements for operation in the challenging conditions of open-pit mining.
The appearance of the 59/80R63 model became a landmark not only for Linglong Tire itself but also for the entire Chinese manufacturing industry. The enterprise officially joined the short list of companies capable of producing 63-inch all-steel tires for special equipment. Previously, only a few factories around the world had such technologies.
During the creation process, the company's specialists solved a number of complex tasks related to design, material formulations, and production stages. Linglong emphasizes that this tire is the result of its own developments, which the company has been advancing for about forty years. Since 1987, when the first tire for agricultural machinery came off the assembly line, the enterprise has formed three key product lines—engineering, agricultural, and industrial—and now ranks among the largest manufacturers in Asia.
The 59/80R63 model features a dense tread pattern that ensures reliable traction even on uneven surfaces. Thanks to multi-channel ventilation grooves and the ultra-low-temperature vulcanization method, heat dissipation is improved, resistance to punctures is increased, and the product's service life is extended. These features allow the tire to function under enormous loads, prolonged heating, and intense impact forces, which are typical for the harsh conditions of open-pit mines.
The launch of the 59/80R63 on the market was a step within the global "3 3" initiative, which is part of the broader corporate plan "7 5". This strategy involves establishing off-highway tire production at three sites in China and three more abroad, which would strengthen Linglong Tire's presence on the global stage. As early as 2022, the company initiated a major upgrade of its plants to meet the growing demand for large-size tires for heavy equipment.
