wa salam, I went for the second option (Upsize Tyre) 185-70-14, so i can only tell you advantage and disadvantage of that. with previous size 185-65-14 it was must that the car would touch breakers, with the upsize now its not must and i can get away nearly all of the speed breakers with 5 people aboard.
disadvantage is that ABS is not what it was before, tyres lock up, before ABS would kick in and do its thing, now it does come in to play but some times tyres get locked up.
slight less disadvantage is about the speedometer, you have to know your actuall speed so you dont get challan for over speeding.
