I guess you could take some calipers and measure the diameter of a tire valve stem; but I really don't see any purpose, unless you just want that information for a game of trivia pursuit.

With GM (government Motors) you can bet there will be different sized valve stems for summer/winter driving, different colors based on what lane and what times you are allowed to drive. Black will no longer be available because it is racist, and the materila will be upgraded so air will no longer leak but each valve stem will cost a million dollars
