Does anyone know if a 245-60-15 tire will fit on the front of a 67 GTX without anyone rubbing/clearance issues? They would be mounted on a standard 15x7 Magnum 500 which if I remember correctly has 4 1/4" backspacing. I would also like to know if a 275-60-15 would fit on the rear mounted on a 15x7 wheel. I'm pretty sure it wouldn't fit on an 8" wide wheel.
