Trying to figure out how to adjust the toe on a second atv. The manual says toe should be Toe-out: 30 ± 15 m. I don’t know what this means. I have used c clamps to attach 2 carpenter squares together and have put marks on the tire and have rotated it 180 degrees. It is toed in right now. does the 15mm mean it should be 15mm difference between the front measurement and the rear? Front being wider to make it toe out?
