4.5" = 114.3 mm The metric equivalent is 115 mm. 115 - 114.3 = 0.7mm, this is the diametral difference. The radial difference is 0.7 / 2 or 0.35mm which multiplied by the inch equivalent of a mm, 0.03937", equals 0.03937 x 0.35 = 0.0138"
14 thousandths of an inch! OMG!!!!!
If this causes a problem with the wheel studs, you'd better crush the car.
