18x9 et 40 235/40/18

Anyone tried running a 9J front on an E89, specifically 18 x 9J ET 40, tire size marginally bigger than standard at 235/40/18.

Standard is 18 x 8j ET 29, will they fit suggests poke is about the same, but sit inboard by circa 15mm - not sure about strut clearance :?

Edit - ignore my rantings, looked at will they fit again and sit 23.7mm further in which (having looked at the car) suggests they’ll hit the strut.

We choose to go to on with this endeavour at this time and do the other things, not because they are easy, but because they are hard…
