Should I measure from the inside front (forward) edge of the rim over to the same on the opposite wheel at hub level, then measure the same from the rearward edge of the rim over to the same place on the opposite wheel? I have heard other ways too. Measure from the center of the tire (not wheel) across front edge and rear edge at hub level. Shouldn't be anymore then 1/8 difference. I know to lean toward plowing the front tires a tad. Does one way sound better then the other? And then I can adjust the steering wheel with a couple twists on the drag link.
