Sticking with the same tire and switching wheels from 15x7 (5.5 BS) to 15x8 (5.5 BS) the tire is going to move out AWAY from the frame.
The change in wheel is changing where the centerline of the tire is relative to the centerline of the wheel.
How much more the tire will stick OUT = less than inch.
