You can run other tire sizes beyond 225/45/17
Most on the site run 215/45/17 because it will leave you rub free near 100% of the time.
225/45/17 will rub on cars with the pre98.5 wheel liners.
I have seen SVT's on 215/40/17 and that looks fine too. Less sidewall means greater probability of damage to your wheel if you hit sumin.
225/40/17 is a rare size but is very doable. Check Nitto tires for this size.
Its your choice...........ALL are acceptable
