Can't keep Secret much longer...

Hey Charley, is that the optional wrinkle wall tire used in drag racing, that GM offered? Anyway, can't say I have ever seen "xray" stamped on any tire. It doesnt surprise me though! I would think a car that is going to pace an event with a large viewing audience, couldn't risk being taken off the track on the hook, or crashing into a wall due to a tire failure.
A local friend of mine who owns a 67 B/B conv., still has a spare like yours only it is a white wall, and has Firestone in raised letters on his wheel weight. Also on that car, with the hood up and looking down at the lower valance panel it says in black crayon, SS 396. This Camaro is also a one owner, original paint car.
Charley, I've got an ad proof of the 67 pace car. In the lower right hand corner it tells where this ad is going to be placed. It says Indianapolis 500 Race Program...May 30, and, Indianapolis 500 Festival Program...May 30. Below that it says "Prepared by" Campbell-Ewald Co. It also has their logo on it. I've had it about 20 years now. Would it be anything you would be interested in??? Lets make a deal!!
