DO NOT BUY. These caps look nice but if you have a metal valve stem they will rust and corrode and stick to the valve! You won't be able to take them off. When I tried to just unscrew these caps they corroded and actually broke my valve stem in half, forcing me to go to a body shop and have new valves installed on all 4 tires! Depending on your vehicle, this is not a cheap procedure. Be careful if you are in a cold/humid environment, I would avoid these caps as they can lead to a lot more problems!
