Different tread patterns of all-steel radial tires produced by Qingdao Double Star Tire Industrial Co., Ltd. have passed tire rolling resistant force test run by China national tire test center.
In order to cope with EU' s "labeling of tires" and meet USA's "Smart Way" certification standard, Doublestar Tire Company recently sent its products taking rolling resistance performance test.
The result demonstrates Double Star tire's excellent safety performance, which may help the company gain acceptance by the market home and abroad.
