What is the correct offset for a 70 Duster with disc brakes. Small bolt pattern rallyes. I measured one of the front wheels and it has a 3 5/8" offset. I am not sure if this is correct. The previous owner put 225/70R14's on all 4 corners. The front tires are rubbing the lower fender lips and inner fenders. I am trying to get a clear direction on new Rallye wheels and tire combinations.

Thanks,

Jason
