when the tire shop removes and replaces wheels make sure they clean the wheel and hub face. If there is a build up of corrosion between the two - it can prevent the wheel from seating properly against the hub face so wheel would appear to be bent - when in fact it's just not seated parallel to the hub properly. Cleaning the hub face and wheel mount face with a wire wheel or scotchbrite pad on a die grinder is not a bad idea, then put something on face to prevent corrosion.
