The Modelhaus makes copies of the SATCO tires in several varieties, I think the red-lines are among them.
Those G78-14s are nice. Those were very common on the 1968-72 A-bodies for tire size; I'd suspect more than a few other cars would've used them, too. The modern size is P215-75®(B )(D)/14, the older size, I think was 7.50-14.
If you mold those tires, Joseph, I'd be in for a set, particularly if you included Darrel's stickers for a choice or red or white-stripe.
