I don't think there is a decent selection of 235s in 15 or 16 w/o the sidewall being too tall.
One of the best handling (and best looking) setups I threw on the SC was 16x7.5 +40 front (215/40) and 16x8 +35 rear (225/40). Great performance, comfy, still lightweight & nimble and that fitment really filled the wheel well too. I only had them mounted for a couple of months so no pics.
