Will they fit

I currently have an X1 and a set of winter wheels/tyres with it. My new X3 is due sometime this winter ... so the question is .. will the 17 inch X1 wheels fit the x3



They are style 318 7.5 17 with ET 35



I appreciate that the tyres are the wrong profile buy if I can just put different size tyres on the X1 rims it would save me a lot of expense



So anyone got any ideas as to whether they will fit ?
