285/35/18s here… They pull in W-grooves hard!
225/45s should fit a 7" rim fine but you may have to increase your ride height slightly so they wont rub.
You could always put a larger tire up front then in back for straight line traction. I did this on my GTP years ago and it worked great. It didnt handle anyway so it was not a concern and it didnt make a noticeable difference. I know a lot of FWD cars have more room in the front wheel wells than the rear… Just another option.
Its only 10mm on each side of the tire so it shouldnt be a huge difference.
