Perhaps someone can educate me on tire width?

I have noticed that most autoX guys are running a wide tire, in the realm of 245 or 255 all around. Several of the track day/hpde/road race guys seem to be opting for a smaller tire, 225 or 235, and getting great results with that set up. As I understand it, the wider tires get you more grip at the cost of more weight. More grip means stiffer springs/bars to combat roll (I think).

So why the difference? And what is a good all-around width for performance? More grip? Less rotational mass? So confusing...
