Jerry Sr. has Bridgestone S-02 Pole Positions on his 348 (205/45-17 frt and 255/45-17 rear) and the rears are worn out (fronts are like new). He does not track the car and does very little aggressive driving. Apparently the S-02's are discontinued and the S-03's are only available in a 255/40-17, not 45. Should he get rid of the fronts as well and buy 4 matching tires (less aggressive w/ better ride quality), or buy 2 rears of a different brand? Thanks, Jerry.
