Assuming wheel wells would be the same 68 GTX to a 70 Satellite I have a 5.5 backspace on a 9.5 wheel. You can't get aggressive with a wide tire with that much wheel. I added a 1/4 spacer on the inside of mine to increase the clearances. I think 5" would be the most you could get away with comfortably. twocents
