Overview

Hai'an Rubber Group Co., Ltd. began its expansion in the second half of 2006. Building on its existing comprehensive tire service offerings, including retreading, repair, inspection, management, and usage, Hai'an Rubber decided to partner with the Beijing Rubber Industry Research and Design Institute and the Qingdao University of Science and Technology's Rubber College. This collaboration aimed to jointly develop high-performance giant engineering radial tire production technology. Through intensive research and breakthroughs in tire structure, rubber formulation, and process technology, Hai'an Rubber achieved significant technological advancements. The company developed the largest domestic 57-inch series of giant engineering radial tire production technology, including six utility model patents (tire film pressing device, storage platform, six-claw hoist, tire stretcher, tire hoist, and bead ring) and eight design patents (tread patterns), as well as 32 other utility model patents. On June 30, 2008, Hai'an Rubber successfully developed and launched its first 37.00R57 giant engineering radial tire. This marked the company’s ownership of the largest 57-inch series of giant engineering radial tire production technology in China, breaking the monopoly of a single foreign entity in this sector.
