Tire size from door jamb decal?

[Baller]

Using a sharp blade, I was able to peel away a lousy green color that was covering the tire pressure sticker. Now my GTX does not have a build sheet and the original owner claims that the car came with steel rims and dog dish caps. My question is, was this tag generic or would it indicate that my car came with F70x14 tires? Thanks.

I believe it was generic. As the decal states, this was just the minimum tire size for the vehicle. If you had a 383 2bbl or smaller engine, the decal would say G78-14.
