I find myself with a 72 Ford van that has 225X75R15 tires. The tread is
good but the tubeless things don't hold much air. 15" tires seem to have
gone the way of the Dodo. I would like to try some inner tubes but have
had trouble finding those also. Any sources for inner tubes that would fit
my tires?
I just orderred 15" tubes from Bumper to Bumper about a month ago. Not a
stock item, but it came in a few days.
