Re: Goodyear tires
<BLOCKQUOTE><font size="1" face="">quote:</font><HR>Originally posted by JoeC: I remember reading something about Chevy Engineering being slow to approve the polyglas tires for high speed applications.

Joe is absolutely correct on this aspect. In fact, Corvettes never used fiberglass belted tires for this very reason. Duntov was quoted as saying that the Corvette required a tire capable of 140 mph speeds and the nylon belted tires were the only ones that met his criteria. Nylon belted tires were used in Corvette applications until they were replaced by radial tires for the 1973 model year. Regards, Stan Falenski

Re: Goodyear tires
From what I can recall, '69 SS Chevelles didn't get Goodyear Polyglas tires. Z/28s got the Goodyear Wide Tread GT tires which were entirely different and totally useless in the traction department. Personal experience.
All I can remember '69 SS Chevelles with was Uniroyal and Firestone but others may have been used.

Re: Goodyear tires
It's not a Chevy, but we just got in a '69 Mercury Cyclone Spoiler, Dan Gurney edition, with original everything, including the spare. It's a no-size on the sidewall Polyglas, F70-14. The car was built 5/69. Again, not Chevy specific, but it helps give an idea of the timeframe of size vs. no-size production by Goodyear in '69.
