Xu Wenying, deputy secretary-general of the China Rubber Industry Association, said that China's tire production in 2011 will increase by 6%, which is lower than the 10% increase in 2010. Xu Wenying said that high raw material prices have increased the pressure on Chinese tire manufacturers and 25% of companies have suffered losses. She said that China's tire exports have also slowed this year. Changzhou Jinxin ARTS & CRAFTS Co.,Ltd , https://www.stageconfettifx.com
