Just to share my own experience:

I used to have 245/275 [9.0 x 19 ET31 F, 10.0 x 19 ET25 R] on stock suspension.
245F rubbed lightly on full lock in the inner wheel well.
275R no rub

I've had to downsize to 235/265 [8.5 x 19 ET32 R, 9.5 x 19 ET28 R] with KW CS coilovers.
235F still experience light rubbing on bumpy roads;
265R no rub

I think you should be fine stock; Fitment with coilovers should be ok too but that will mostly depend on the coilovers you get.
