I have purchased 4 different sets of tires from this company. On two occasions both sets failed long before they rached anywhere near their tread life. I had purchased a set of Continentals and a set of Nankang. Each instance the company made me jump through hoops, never doing anything about compensation, blaming the manufacturer, and saying they are helpless. The manage a female is the worst of them alll, no people skills no sense of customer satisfaction. NOW WONDER THEY HAVE AN F WITH THE BBB
