I have an opportunity to upgrade my 19" Style 212 255/50 R19 to 213 255/50 R19 and 285/45 R19 for a good price. Question is can I just put these straight on... looks like the rears are not wide enough to need the flared wheel arches... how does going from a 255/50 R19 rear to a 285/45 R19 rear affect the car.. I would think it would it would affect something as I'm going from a 50 profile to 45 profile on the same size rim ? Thanks !!!
