Passenger car tyres account for the majority of Qingdao-based tyre maker Aufine Group’s production, and company general manager David Sun shares that Aufine is now selling these products throughout all of Europe. One range that is selling particularly well within the region is the new Aufine winter car tyre line, the Supergrip S1, which is manufactured in 19 sizes for 13 to 17-inch rim diameters.
