I went to the Goodyear website a couple of years ago to check if 4 F70 x 14 Goodyear Polyglas RWL tires I had were original or original replacements. I gave them the codes off the 4 tires. They sent me a response with the answer and told me where they were mfg. Don't know if they can break down the entire coding though. You could also try Kelsey Tire to see what they might be able to offer.
