15 & 16 inch they can handle on car & light truck tire machine. 17.5 are basically a small transport tire and rim. The screw in valves are the same as a transport . I found the shorter stems at a steam show in Portland Indiana. It is a bit hard to find just the seals as they prefer to sell new stem with the new seal on it. The long five inch ones are quite easy to come by but the short ones not as popular. I'm thinking the ones that came on my DRV were 2 inch and the ones I picked up in Portland were 1 1/2 which I prefer to add tire pressure monitoring sensors The seals don't need changing until they leak and if they start it will be a very slow leak.
