To find the exact backspacing, you need to look at one of these sources:
* The wheel itself: The backspacing will be stamped or cast onto the back of the wheel.
* Your vehicle's documentation: Your owner's manual or any paperwork that came with your Jeep might list the specifications.
* A reputable tire shop or parts store: Provide them with your Jeep's year, make, and model, and they can usually look up the specifications for you. If you have the stock wheels, taking one to a shop allows for direct measurement.
Without access to one of these sources, I cannot give you a definitive answer.
