Shandong Yongsheng Rubber Group released price raising notice on April 7.
The company said that all of tire production would lift 2%-3% of price since April 8.
The company gave the same reason with other tire manufacturers that raw materials' price like natural rubber, carbon black and etc., has climbed up, which largely increased tire cost.
Since March, there were at least ten tire brands releasing price raising notices.
Yongsheng Rubber is one of large tire producers in Guangrao, Shandong Province, and bought out Hengyu Rubber's factory not long before.
