Glen, if you can help me out, with photo's
. A common misnomer about the "Goodyear Billboard" tires. Between the 60's (Say 63-70) no race or street Cobra every wore the so-called Billboards. The tire used again in the 60's was called a "Goodyear Blue Steak Sports Car Special" (A pure race tire, that was sometime used on the street too). A thin (maybe 1/4 inch) blue line around the edge of the tire, with 1" lettering in white that said "Goodyear" These were not raised letter's. The whole Billboard or raised white letter's craze, came in the 70's when Goodyear became the official NASCAR tire, and wanted it well known who's tires were on every car in the field, there even came a time (70's) that the Goodyear logo, had to be proudly displayed on all 4-fender's of a NASCAR too. Such was the start of "Big Time" advertising in the racing world. Hope this help's a little. Cheers Tom.
