Goodyear Tires

And when did they change to DOT from a non-DOT tire.

I bought a 69 Indy Pace Car in 1981 from the Chevy dealer that owned it from the time it was new. It had four polyglass tires and a non-polyglass spare. When I asked the dealer about this he told me that he could not order the good polyglass tires and changed all of them but the spare when the car arrived.
The spare was a Speedway Special. Charlie has that original spare in his barn now. Unfortunately, that's all that's left of the car.
