[VAC] Re: New to list

["Dr. Gerald N. Johnson, electrical engineer" <geraldj@xxxxxxxxxx>]

6.70-15 and 7.75-15 are essentially the same size. 6.70 was the
preferred designation for the tire tread width before some time in the
60s when tire sizes were changed to reflect the width of the fattest
part of the tire. The normal maximum width of the 7.75 tire is the same
as the normal maximum width of the 6.70 tire. Its still important to
carefully select the tire because modern equivalents, especially radial
tend to be a little wider, just enough to not fit in the Caravel wheel
well. Nearly every VAC owner has had to try more than one tire to find
one to fit.
