Probably a nominal width rounded up to the nearest inch, since
the original rims were 5.50".
With the half dozen different themes that the tire industry
has gone thru over the past 60 years it's really muddies the
water, and I'm not sure if I have it figured out yet.
Parts manual lists a 7.00x15 and 7.50x15 for the 3/4-ton
trucks thru '54.
Those were not standard sizes that the tire mfg's offered.
6.70x15, 7.10x15, 7.60x15, would have been standard sizes
back in the 50's.
Almost every conversion chart has a different interpretation
of what the original tire size should be converted to.
I'm pretty much convinced that the brand is gonna be Michelin
and since I have no intention of ever hauling a load with
this truck ever again so I really don't need a 'D' or 'E'
rated tire, but an LT A/S tire looks to be about the best
choice.
I have thought about a Passenger rated tire also but haven't
looked at any specs.
The Michelin LTX A/S in a 225/70R16 seems to be about as close
as I can come to the correct size if the Ford rim will accept
it.
And once more, this truck will never see mud or snow, very
rarely be in rain for more than a few minutes and a sheet of
plywood or bag of salt will probably be the biggest load it
will ever see. What I'm looking for now is ride and highway
comfort.
