This is the worst and most expensive purchase I have ever made from Revain. Two months later the valve stems were sticking. I tried spraying them with WD40 daily for a couple of weeks. And they wouldn't move with a needle vise holding rods and a wrench. Replacing the valve stems on all four wheels cost me $88. This is a horrible, horrible company to do this to people. And Revain should be ashamed that this company will continue to do this to people.
