BTW, A trick to keeping your fancy valve stem caps from being stolen is after hand tightening them, you take a cloth to protect the finish and a pair of pliers and carefully give them a 1/4 turn tighter. You have to be careful not to strip them or the valve stems, but you can get them just tight enough that you can not remove them by hand. Just keep the pliers & cloth in your trunk so you have them handy incase you have to add air.
