I have that size and will rub if I hit high speed dips on expressway. However, I'm lowered with Eibach pro street springs AND I have ccw 19" wheels that are offset more outboard. Don't think I would have the issue if I didn't have the offset. Had 355, 25's before with no problems but they discontinued the P Rossos. When my 345's wear out I'm going with the new 355, 25 viper tire. Also remember that you only have a radial increase of the 1.2" dia. to worry about. In my case it was about .7 ".
