Can someone explain to me what offset does? I understand backspacing, just not offset. Does negative offset make your wheels stick out more or less?
 
Offset is the location of the wheel mounting surface in relation to the true center of the wheel......normally in mm.
Negative does move it inward.

So....

A 20x10 wheel with a 4.5" BackSpace will have approx -24 or -25mm offset.
A 20x12 wheel with a 4.5" BackSpace will have approx -51mm offset.


FYI, 25.4mm=1"
