The 15x6.5" wheel would be 1/4" wider on each side, not 1/2" on the outside.
If the .5" were just on the outside, then the centerline of the wheel(the spot where offset is calculated) would differ, and offset would change.
Offest is the distance from the mounting pad(where you bolt the wheel up to the vehicle's hub) to the exact center(centerline) of the wheel.
So, a wheel with OEM offset, and 1/4" increase in width to each side will look almost identical to factory. What he said!!
