Back space to offset?
Most XXRs will require spacers.
0 offset on a wheel means the mounting pad is directly in the center of the wheel.
9.5" wheel is 10.5" overall.
0 offset on a 9.5 is 10.5/2 = 5.25" BS.
Positive offset adds to back spacing. +25mm offset is about 6.25" BS.
Hope that helps anyone else wondering

Here's the best wheel calculator I have seen, Offset in mm to BackSpace in inches is real easy.
