Fresh today 2 sets of Michelin pilot sport 5 205/40ZR17 and 2 2015/45ZR17

This is my first set of tires since I've bought the car and had 205/40ZR17 front (Kumho ecsta) and 225/35ZR17 (same brand) and I'm not sure if I use a square setup or if I keep this 17's or replace them for 16's and what wheels.

And if you guys recommend something make sure to help
