Review on Dsycar 12 Pack Tire Stem Valve Caps Black, Thin Blue Line American Flag Hexagon Shape Design, Premium Metal Aluminum Rubber Seal Tire Valve Stem Caps ,Universal Fit (Mini - Black Blue USA) by Inyong Dow

I installed these valve stem covers last spring and I when I recently went to add air to my tires I realized that all the covers totally corroded sealed themselves onto the valve stems. Was able to get a couple of them off woth vice grips / pliers. Just be aware that once you install you may not be able to get them back off.
