About Chaoyang
The Chaoyang brand comes from the Hangzhou rubber factory set up in 1958 near the Qiantang River and the Haichao Temple. The factory began with bicycle tyres and grew into Zhongce Rubber Group. Modern Tire Dealer noted in 2018 that the group had passed 4 billion US dollars in revenue. Hangzhou city government reported 2024 revenue above 39 billion yuan and net profit of 3.78 billion yuan.
Zhongce floated on the Shanghai Stock Exchange on 5 June 2025 and raised about 4.07 billion yuan. Hangzhou officials called it the largest A-share listing of the year to that date. The money is earmarked for plants in Hangzhou, Tianjin, Jiande and Thailand. The company reported that annual two-wheel tyre capacity reached 94.1 million units in 2017.

Sourcing Chaoyang from China
Chaoyang shares pattern codes such as RP28, SA37 and CR960A with Westlake and Goodride. An importer can often get the same tyre under several names. The Rayong plant in Thailand lists Chaoyang among its five brands, which gives a second origin. Loading quantity, lead time and minimum order depend on your size mix.
