On the rear wheels, I want the center/hub of the wheel centered up in the wheel regardless of total width needed.
Why? Do you want the wheel back spacing to be in the center of the wheel width exactly, IE 10 inch wide wheel with 5.0 back spacing? Centered or negative offset makes them harder to put on and take off usually, the wider the wheels and tires the worst the problems Been down that road more than once due to NHRA rules in NHRA stock classes years ago
