The 1998 Ford F250 Lariat 2wd bolt pattern is 7-150 mm. This means there are 7 lugs and the diameter of the circle that the lugs make up measures 150 mm or 5.9 inches across. To get a close measurement of your 7 lug bolt pattern without a bolt pattern tool you should measure from the center of one lug to the outer edge of the lug furthest from it.
