Hey 1955_chevy_6400, I have a 1955 6100 2nd series that came with 3 piece 20" rims. I read the tech article Grigg , Mike B and others put together and decided to go with the 22.5" rims off a 56-59 1 1/2 ton chevy. Tube tire seem to rust inside more easily than tubeless. So I think the 22.5" are a safer bet rust wise. I searched everywhere, craigslist, ebay, junkyards, I ask friends and stopped at many a farm along the roadside. I found a set for $35 apiece plus shipping and that include removal of the tires. It came out to about $65 a wheel and no rust problems. I like searching, it's part of the fun. Put an ad on craigslist and see if you get lucky. There's a set of wheels out there for you somewhere. Good luck! SEE YA! Mark
