Switching from 19s RFTs to 18 non-run flats improved my G30 ride comfort. Especially over potholes and larger impacts. The car is just more enjoyable to drive now. Just switching to non-run flats will help too if you don't want to spend the money for new wheels.

My winter set up is Goodyear Ultragrip Performance still mounted on my old 19s and they are night and day smoother and quieter than the old 19in OEM Goodyear RFTs were.
