I have been asked by several folks about the offset so I measured the wheels and they are 7 inches wide. The back spacing is 4.25 inches. So if i do the math correctly, 7/2 = 3.5 which is the centerline. If you subtract the centerline from the back-spacing you get the offset so we have 4.25-3.5 = .75 or 3/4 of an inch. The offset is 3/4 of an inch.
