Wheel and tire sizes for 65 GTO ?

The 65 GTO I am restoring came with 14 x 7 rims on the Front and 15 x 7 rims on the back when I bought the car. The Wheels are an old set of Cragers. I want to put Pontiac Rally One Wheels on the car. My question is, will 15 inch rims work on the front of the car? I don't want to put 14 inch rims all the way around the car as the engine is very powerful and I have a 3.73 Rear. Also I just put the correct gear on the Trans. Tailshaft and speedometer gear in to make the speedometer correct with that rear ratio and 15 inch tire size. If I don't put 15 inch rims back on the rear of the car the speedometer will be off again. I like the look of the 15 inch rims on the back and I don't want 15's on the rear and 14's on the front. Does anyone know if you can put 15 inch rims all the way around and what are the limitations on the width of the rim and tire size? Will the front wheels and tire clear the wheelwell when turning to the extreme left or right. Any help is really appreciated.

The original 14 inch tires had an overall diameter if 27.02 inches and were 7.6 inches wide. If you run your 15 inch wheels you can have 215/70-15 and have the overall diameter of 26.9 inches and 8.5 inches wide. The diameter is very close to the original but much wider tires ( you need for your power). Most people I have talked to say this is the best for the 65 GTO with the 15's. If you go to 225/70-15 the diameter now is 27.4 and you are now wider at 8.9 inches. 65 owners with this tire have said that the front tires will rub when the steering wheel is fully deflected or during hard turns.

I have 15x7 rally I's all around on my '65. Tires are 205/75/15 Coker Redlines. No rubbing problems at all.
