You bring to mind other variations in whitewall geometry by tire line. Typically the Original Equipment changed first, followed by the next level up - typically the same or nearly the same tire design but nylon cord instead of rayon - see Custom Power Cushion (Nylon or later Vytacord) vs Power Cushion (Rayon or later Polyester). The lower level tires frequently did not get the latest whitewalls for a couple of years if at all.
As an example, only the 1970-71 OE level bias belted were ever dual whitewall (a few non standard geometry exceptions noted - Goodrich Lifesaver, General Dual 90, etc). The upper level tires stayed single whitewall as did the lower level tires.
And frequently the highest level were distinctly odd whitewalls - dual, triple, radial white lines inboard, etc to distinguish the tire snob and discourage going to another dealer when you needed new tires.
Rich - just wondering if your spare is square shoulder with sharp
corners in tread groves or rounded shoulder with less distinct
changes in groove like seen in the 1966 catalog you refer to. The
former should have been an 8.50-14, the later an 8.55-14.
You are making me rething my timeline - I had been pretty sure
the narrower whitewall came in later than 1964 but maybe it just
moved outward later.
