What vintage? Formula 1 Super Stock tires

[jeffschevelle]

Got two of these tires on a set of old Cragar skinnies I bought. Anyone know what is the approx. year range these tires would have been sold new? They are in great shape (other than dirty), so I would like to put on the Ansens on my 43 mile 67 Chevelle day-2 drag car if the tires are not "way too new". (They'd be better than what is on there now either way though.)

And if I do use them, I have a poll - Would you turn the white letters out, or run the blackwall side out? A couple pics of the car are included. Last pic is after professional wet sanding and buffing this weekend of the 100% original paint. (Still to be final hand rubbed and waxed!) Still has all the nicks and scratches from 4+ decades stored in a garage with junk piled all over it, but at least it's slick now!

Thanks! Jeff
