A tire that has been run flat has just been removed from an Alcoa aluminum rim. Technician A states to roll the rim on a flat level surface for a minimum distance of 10 feet to ensure that it rolls in a straight line. Technician B states to use a square to ensure that there is no more than .030 gap between the square and the rim flange. Who is correct?
