Go with 205/40/17 tyres and you won't get any rubbing with a 7x17" wheel. Maybe a little at the rear when you've got 2 people in the back, but that's about it. Interestingly enough, I've found that certain makes of tyres are more prone to rubbing than others. Toyo Proxes T1-S don't rub at all, whereas Yokohama A539s rub loads. Same size in both cases, 205/40/17...
