2010 Chrysler 300 Touring - Shopping for tires and wheels
 

I recently purchased a 2010 Chrsyler 300 Touring. I need new tires, and want to upgrade my wheels. It has factory seventeens on it now. I saw a newer model 300 with 245/45R20/99V/M+S tires on it, and I like the look. Will that size tire and wheel fit on my 2010? Not a big Firestone fan, so I probably won't be buying the Firehawks, but I am concerned about backspacing and fenderwell clearance. Is the overall height pretty much the same? Any help would be greatly appreciated. Thank you so much!

Thanks to the 110 folks who looked at this thread so far. I appreciate the robust response and debate. Have a great day everyone!
