You mention in another thread that Michelin was wrong about the factory specs. So you already understand that they can be incorrect. I've stated my opinion about Tire width and rim width. You've added a whole bunch of other stuff in with your assumptions. I understand you want to give OP all the information so he can make an educated choice on what tire and wheel he adds to his car. Thats Great! And some guys run 17x9 with 245, even though YOU think it does not increase performance.
Additionally, IMO, you decided to not get rims on a basis of budget. NO race team uses stock wheels. So obviously, there are better wheels than stock performance wise.
Good luck!
This has been a fun back and forth, I hope you don't feel personally attacked. Everyone is entitled to their opinion, and I have been posting mine here in the wheels/tires section for almost 6 years. Thanks for sharing yours.

When a manufacturer like Michelin gives a range of wheel widths, I've found that the fit is just fine on their range. Within that range, I'd agree that 7.5 for 225's is a "perfect" fit, but I wouldn't go with less width just because I had a 7" rim. And I wouldn't say to anyone that you shouldn't put 225's on a 7" rim. I can tell you from experience, the fit on a 7" rim is extremely good.
Just because someone runs with 10.5" width rims and 265's doesn't mean it's the best performing setup. In fact, there is a lot of evidence that putting anything wider than 225's on the front reduces handling. Extra wide wheels and tires also weigh a lot more. If there were evidence that putting 245's on this car improved performance for a street daily driver, I'd get new wheels and tires in a snap.
While there may be some errors in the Michelin specs, I've found them to be far and few between. And when there is an error, it is a large one like the weight of the 225/45/17 PS4S. That error is really obvious. Over the years, I've never found an error in rim width and I've purchased hundreds of Michelin tires....
