this reminds me of the time in the early 70's when i bought all the wide white wall tires from the local tire shop.
these were tires they had for many years and couldn't sell. by then, most of the blue stuff that was supposed to protect the white wall until mounted and washed off had disappeared from moving around over the years.
although somewhat dirty, the white was, well, still white.
after a little cleaning, these things looked great.
since this was way before the interwebs, i advertised them in hemmings, and made a good buck, selling all of them pretty quickly.
