Third pic is a tire that is supposed to be orig. It is on my Z28 and has been there for 18 years. It is supposedly a orig. tire and not a repo. It says "Vytacord Polyester cord".. Any info or opinions ?

Does it show "Made in the USA" anywhere on it?
I found this under GoodYear Tire History:

"1962 New chemical plant started in Le Havre, France....Vytacord polyester cord announced....Research scientists discovered sprayable polyurethane rubber....Goodyear Aircraft awarded new government contracts, including one for development of high resolution radar for world's fastest fighter plane....Super Single tire and rim announced as replacement for duals on trucks....Goodyear racing tires used on more winning stock and sports cars than any other brand."

What are the build date codes on the tires? Those numbers are melted into the sidewall near the bead during the curing process.

General question: Do all the repo's tires have current dates to comply with DOT regs.?
