I'm going to go with all over the board. For the most part I've heard 23/25, but I prefer it much higher. When I autocross I run 42/44 and keep it in the high 30's afterward. Most people like it lower as it provides some softness in the ride and when air pressures are up the car could be a bit darty, but I don't find this to be the case.
