I wouldn’t think so. Lower the rears if you’re finding the ride harsh. Don’t forget to reset the TPMS after (page 148). FWIW I checked mine yesterday and my 205s are set at the 195 pressures (35/32) from the dealership. Will pump them up today.
On the roads around here, on 205/45, that would definitely shake my fillings loose. When I used to do long distance runs in the smart CDI, I’d bump the tires up to 40 and that was freaking harsh with the Bilstein coilover suspension.
