I have been running radial (Diamondback) tires on stock '35, 16" wire wheels using tubes rated for radial tires. There is a small plastic spacer available that fits in the valve stem hole in the rim that protects the valve stem on the tube to prevent what happened on Vic's car. I have over 20,000 miles on these tires now, that are on my Avatar car, with no problems whatsoever. My preference is to run tubes rated for ratial tires with the radials on my cars, but there are many success stories of those who run radials tubeless on these old Ford wheels.
