I don't think I ever asked this question here yet, so here goes. The 225 currently has chrome road wheels, but 3 are the 7"ers and 1 is a 6". I currenlty have the 6" on the driver rear of the car (non-posi), and have not had any problems for over year and a half. The question is, can the 6" be used up front as well? I ask because I would like to rotate the tires as off-front alignment is starting to cause inside of driver front and outside of passenger front tires to wear fast (car pulls to the right). Even if I get an alignment done (not sure how much it'll help because I have a couple of shot front bushings and I did actually have one this past winter which helped a little, but now it seems worse again) I would like to rotate and it sure would be easier if I didn't have to take off tires. Plus I'd like to try and save up $$ for snow tires to put on the steels. Hope that made sense.
I can't imagine any serious problems because of a difference in rim width. I'd imagine you are just using it as a driver/cruiser, and not seriously pounding it through corners. I don't think tou'll find a shop that will even attempt a front end alignment until all the worn parts are replaced. It would be a waste of money anyhow. Your 6 incher should perform without a problem. Save some cash and then get it done right! :beer
