An implied aspect of his question was about going to square set up which then puts a 265/275 in the front versus 245 IIRC. My experience is that when I went to wider tires in front, I got a lot more bite and had to adjust some of my turn in points as the car was much more neutral. Turn 14 at TWS was a prime example, where I used to chop it hard with smaller front tires, but once I had the wider tires I almost ran over the curb with same input.
