Then it depends on the offset. An Alltrack with 18" wheels has a 225 tire and there's plenty of room but the offset might be different for a 17" as compared to an 18". The only real problem I could see is it rubbing on the inside (i.e. the front strut).
It is interesting because in the Continental series, we all run 225/45/17. The FWD guys will run a 9.5" on the front and a 7" on the rear. It actually makes a difference mostly because they want the car to rotate (which also explains the 2000lb rear springs, no rear camber and zero toe at the rear). I always ran a 9" on my BMW and with the offset, had to shoehorn it in there with some creative work with the rear inner fender wells.
