Hello again.
The spare tire in my '67 convertible has a "DG" rally (NOT "DC") with a "virtually" unused tire (although the back of the rim shows this tire has been on a car). This tire is the same one that is shown in the Dobbins Vette Vues book for a '67, but he doesn't mention DOT codes for a '67. It is a Uniroyal Laredo whitewall with what I think is a DOT marking (stamped into the backside of the tire) of "GT7788". I know how to decode current tire-dating codes, but this code doesn't fit with current coding structure. Can anyone help with this code?
Did original '67 tires have a DOT code?
The other info. on the tire is as follows (all raised type): 7.75-15, 1738-420, 66 AC 38. Under Uniroyal (which is boxed) it says U.S. Rubber, and on the back side of the tire it says "the rain tire".
