I've got the stock 8-bolt rims on the 1948 dually. Half the tires should have been retired in the 70s. The other half seem OK but I don't think it would hurt to replace them. They are all rock hard.

Not finding much in the way of used bias ply 700x18s. Coker wants north of $200/each for them. My buddy at the auto garage said I'd be better off just ditching the rims/tires that I have and finding something more modern that would fit. I'm sure a modern 8-bolt setup would work in the front, but what have people done about the back? Just looking for options/ideas so I can start watching craigslist for a bargain.

Or -- could I mount radials on these rims w/ tubes? Anyone know the size conversion?
