George, I believe for the 1972-77 Panteras a Pirelli CN12 215/60/15 would be exactly OEM with a height of 25". The 205/60 is 2% smaller than OEM.
I believe such a tire would make a great impact within the Pantera community, making it possible to use the original (my first choice) wheels again. Anyone else out there interested?
Dougal, what would it take to convince Pirelli to manufacture a CN12 for the front of the Pantera?
