i think you'll find a 235/45R17 is completely legal on widths from 7.5" up to 9", with 8" being the apparent optimum width.
not to mention a 235 is the largest tyre i can fit on those rims without having issues with rubbing etc, also from a price point of view they are the best bang for your buck.
so in your opinion it's too small, and you don't like my wing.. that's fine, i setup my cars how I like them, and if other people approve, then that's just a bonus.
ps, can you please point out which part of the rim is exposed in the below picture?
