My Ranger has one wheel just slightly bent, not much, but at 70 mph it begins to shimmy a little if put on the front, less so on the back. Consequently, I can't rotate the tires and will soon be needing new ones. Have looked all over for replacements but unable to find one that matches....its basically a steel rim but with a chrome face on it. Are there any places that can straighten a wheel? If not, is it likely that it could be improved by getting it balanced on one of the Hunter "range force"? machines?
