Measuring Backspacing

When you're shopping for aftermarket wheels, you'll see a range of backspacing, offset and width measurements available for your vehicle. When looking at wheels, sometimes we'll have the measurements from your stock wheels, but sometimes we do not. This may lead you to wonder, "How are these measurements going to change the stance of my car?" While all of the wheels listed for your vehicle are guaranteed to fit, without knowing what you currently have, it's tough to know how far in or out your new wheels will sit. If the offset is not stamped on the back side of your wheel and your research has you still feeling empty, you can measure the backspacing of your current wheels at home.

Here's how:

  1. Remove one of your wheels, just as if you were changing a spare tire.
  2. Put a jack stand under your vehicle to support it while the wheel is off.
  3. Place the wheel, face down, on the ground (preferably on a towel or blanket so you don't scratch it)
  4. Get a straight edge that will span from lip to lip (see red in diagram below).
  5. Measure from the bottom of the straight edge straight down to the mounting face of the wheel (see green in diagram below).

If the wheels you're looking at have the same width and a higher backspacing measurement than you currently own, the wheel will sit further back in the wheelwell. If the width is the same and the backspacing is lower than your current wheels, the wheel will stick out further.
