THanks alot truckdog. From my reading of the first chart, 32x6.00 was a 20x4.5 rim and from the second chart, that makes them a 6.50 width since the 4.50 falls between the recommended and permissible.
I think that makes the tire size 20x6.50 even though the back ones are 7.00x20's. They do look a little bulgier.(new word) What the modern code would be is the next step but thanks for your help.
