I cant remember if its 30 or 35 mate.... 30 was more prominent in my mind for some reason. Might be 35 profile now you mention it as I think the front is 215 35 and the rears are wider but same profile, I only know this cos I asked her what size tyre she needed for the rear of her car and she took the size from a front and when I went to fit it realised the dozy moo has wider on the rears . I may be getting confused with my M5 as that had 35 profile front and 30 rear. If she's online she, might, be able to tell you
