SBP 14" Steelies & 195/75/14s

Are you measuring the inner bead where the tire mounts to, or the lip edge that rests against the tire? The bead area is where you get the diameter of the rim, and can only be measured when the tire is off! If you are measuring with the tire on and measuring from lip edge to lip edge, you are not measuring the correct diameter! From the looks of the rims in the pic, they are 14x4.5", SBP rims!!
