So I found the wheels upgrade I want. They are non staggered 17inch x 8's...

My question is what are the widest tires I can use without scraping the front inside wheel well when turning? 45's? 40's? Someone with experience who has went form 16's to 17 inch wheels and tires will know. The tires (and wheels) I have now are too small. I don't want to fudge with the suspension at least not a LOT and not at all if I can get away with and would accept a smaller turning radius (carefully in parking lots, etc.) if I had to to get the absolute widest tires for this application.

I'm going to go with close to the best Michelin Pilots but not the top of the line summer tires (PS4's but maybe the next best touring tire) as I will drive it in the Winter on those clear blue sky crisp DRY weather days because as we ALL know, these cars need to be driven and these M62's (and S62's) are SO MUCH FUN TO DRIIIIVE!!!

Thanks in advance everyone!
