tire mfg date?
I got a set of NOS G7014 red line tires with this GTO that I'm working on. They are old (USA made), but I'm not sure how old. There is a DOT impression just before the mfg/date code Aug 89? Oct 69? Any assistance would be appreciated.

So, according to Coker web site - could be the 8th week of 1969. Since they are US made - I don't think they would be '79. '89' 0r '99. Could be wrong though. Anybody else have input?

Looks like this tire was manufactured 8th week of 1979 (thanks Darrell). It can't be 69 because it is a DOT tire. Can't be 89 or later because the manufacturing went off shore in the 80s (this tire says USA mfg). Interesting to note though - the red line on these old tires is quite a bit narrower that then repro red lines - see pictures. Does anyone know if the narrower red stripe is available today?

stripes on the NOS Polyglas tires measure approx 5/16 wide - repro Polyglas stripe width is approx 7/16 wide. Do the show judges out there pay any attention to stripe width in determining correctness?
