Well, I was wrong, the factory 7" wheel has 4" backspace at the bead and 4 1/2" at the lip. I took a few pics to show where I measured from.
First is at the bead...4"



Second is the overall setback of the tire... almost 5 3/4" This is the distance you need to know for clearance anyway. Having a narrower tire will provide more backspace. I couldn't get the camara down level on these pics to accurately show the measurement.



Third, you can see how much sidewall bulge is present with the 7" wheel. This will straighten up quite a bit with an 8" wheel.



I put this on the car to check for fender and frame clearance. Tire to frame is 1 1/2"



Tire to inner wheel well is close...1/2"
The 275x60x15's I have are on another car, a 1966 Chevelle and they are close but don't rub. It is 30 miles away in storage for the winter. Adding another inch to the wheel width and going with the 5" backspace that fiesta62 has should be good. If in doubt, consider a 255x60 tire but be aware that it is almost 2" shorter than a 275x60

I test fitted a 15X8 Corvette rally on the car with a MT 275/60 Drag Radial... and there is no way the outside lip would not rub... I had about 2.5 inches to the inside frame rail. The guy wants to be able to rotate the tires..so different offsets on front and back wheels is a No Go. I think the 15X7 wheels with 245/60's will work on the front and rear... and still be stock appearing and not rub in the front or back....and not rub the aftermarket disc brakes in the rear......

A corvette wheel has a shallow offset....more wheel to the outside. Either way, if he wants to rotate tires, he needs to stay with a 235x60. They will rub slightly on the frame at full turn in front and a 245 will rub big time.

Looks good......nice stance and the tires are wide enough to add attitude.
