pilot sports are also a very good tyre mate - IMO
there are probably a few that wont agree, thats the general way with tyres!
iv only driven M3's with them on, and 335i's and d's. and they were up to the task!
they can tell in daylight, take it to an MOT test station, your garage probs has one, they will use the headlamp alignment equipment!
and youll be all good!
