Best bet is to jack up the front and take the wheels off and then youll see exactly where theyre rubbing. Ive had to leave all my sh*tguards off and angle-grind a bit of the metal out of the inner arch, but on 17s you probably wont have to be as drastic. The top sh*tguards can come out safely, with the inner one what you can do is take it out, cut it so that it just covers the belts and then mount it back into the arch again.
Remember that the wiring for the side repeaters is usually protected by the upper sh*tguard and the brake wear sensor wire is protected by the inner one so cable tie these well out of the way.
