I have 19" rear and 18" front Pilot sport runflats currently and a new set of Pirelli Pzero 355s as a replacement set. My rears are needing replacement but fronts are fine. Is it OK to have the 19" Pzeros on the back and 18" Pilots on the front or should I buy a new set of Pirelli 18" fronts and change all as a set?? I dont track the car ...just street driving.
