What is Backspacing?
An important part of shopping for wheels is knowing your backspacing measurement. This is the space between your wheel's mounting surface and the wheel's inner lip. Vehicle manufacturers have a minimum backspacing requirement so that, when mounted, the wheel does not interfere with brake and suspension components.
Find Your Backspacing Measurement
To get your current backspacing measurement, measure from the wheel mount surface to the inner lip of the wheel. If you are buying a set of aftermarket wheels but keeping your suspension the same, you should try to keep the measurement as close as possible to your stock backspacing.
