So Bill,
I have a '55.1 and want to put a tire on it whose footprint is a little larger than the stock 4" wide wheels I have. Are you saying that I can put any 16" wheel that will fit an '87 1/2 ton Chevy 4X4 on my AD truck? And 4 1/2 inches is the offset I need? Can't for the life of me remember what the Blazer Rallye wheels look like, but I'm searching for a low budget answer to this problem. How wide is that Blazer wheel BTW?
