Not sure how much different a 215 will sit on a 17 than it does on my 15x6 rims, but I have 215/60R15 Yokohama AVID H4s and they rub slightly in the front when the wheel is locked. I have never felt or heard it rub but there are rub marks on my inner fender. It is very light rubbing. I would think that 225s would rub alot more, however the GLI runs 225s I believe so it must be possible...unless the GLI has different inner fender liners...
my 215/60 tires should technically stand 1/3 of an inch taller than the stock Michelins, however they actually sit almost exactly the same as the speedometer reads slightly fast still.
