The government launched a number of policies to assist tire companies
2018 is coming to an end. Many tire people sighed and said that the past year, the days are not very good.
The price of rubber continues to rise, and the price increase of tires is a foregone conclusion.
[Hui Cong Auto Supplies Network] As the production of tires continued to rise, especially the natural rubber rose from 9,000 yuan / ton to 21,000 yuan / ton, natural rubber increased by 110% in three months. At present, most tire companies have already issued price increase notices, including many international first-line brands.
