OEM diameter = 26", 225/45/17=25"
with 225/45/17, handling and acceleration from a dig would be better, however your speedo will read way higher than actual and you will accrue more mileage than actual. visually you will increase the wheel gap 0.5"=13mm and total vehicle height will be 13mm lower as well. i wouldn't go this size

i recommend
235/50/17(26.3") or
245/45/17(25.7") however, since min rim width for 245/45/17 is 7.5", it is slightly pinched which results in sidewalls that are a slightly bulged. this is still within spec, though.
