Please explain backspacing. I think my '04 wrangler came with 3.75" backspacing on the stock aluminum wheels. I'm running 33's and want get rid of my spacers. Thanks, Ernie

Asked by Ernie from pinetop, az on

Hello! Backspacing can be easily measured on a rim that is off of your Jeep by doing the following. You'll need a flat piece of steel or wood. Use the flat steel or wood and lay it across the entire width of the rim. Take a measuring tape and measure from the flat wheel mounting surface (where the wheel mounts flat to the axle) to the flat material. This is the backspacing of the rim.
