Hate to bring up the subject again but I a relatively new to the E60 forum and a new 550i owner. I am considering new rims and would like input on fitment. I am looking at swapping some 7 series rims for my current 18 inch stocks. I have an 07 550i with sport suspension. No other mods. Can someone enlighten me on whether rims with the following sizes will fit and if so, what the optimal tire size is that wont rub. I do not want to have to roll the fenders

Front 9x20 ET 24
Rear 10x20 ET 24

thanks
