I saw the question about tires in a earlier post, i would like to upgrade my wheels from 17.5 to late model 16 inch, with modern radial tires. Do say 70-90's 8 lug chevy wheels fit a 59 3800 1 ton? Is the patern the same? If not what modern radial tire size crosses to a 17.5" wheel?? I don't want to spend big bucks to replace 50 year old bias tires with new old style bias tires.
