The 2011 Saab 9-4X 3.0i Aero XWD bolt pattern is 6-120 mm. This means there are 6 lugs and the diameter of the circle that the lugs make up measures 120 mm or 4.72 inches across. To get a close measurement of your 6 lug bolt pattern without a bolt pattern tool you should measure from the center of one lug to the center of the lug across from it.
