Mar 12-19, 2016 EVERICH TIRE sales team visited the mines in Guang Ninh, Vietnam. By our visiting, we know Vietnam mine is similar with Inner Mongolia mine. We are almost NO. 1 mining tyre in China. So we are confident in our OTR tyres. Facts proved our OTR tyres can run 5 months in Vietnam and normal Chinese brands could only run 2 months.
