Summer tyres/wheels Volvo V40 T3 R-Design MJ 2018

Hello together, with me this year new summer tyres are due. Since I see my car in winter with 205/55 R16 tyres as much more comfortable than with the summer tyres with 225/45 R17, I am now faced with the decision to buy new 16 inch complete wheels or simply to have new tyres put on the 17 inch rims. In front of me: I know that the V40 has a rather tight suspension. In addition, the effects of tyre dimensions on the driving behaviour are far and wide clear to me. But: Is it possible to achieve a more comfortable driving behaviour (with the same dimensions) of the vehicle with tyres of other manufacturers (currently: ContiSportContact 5 225/45 R17 91W? If yes, which are recommended here?
