Are you talking pavement or gravel?
I've wondered if some of the pro crashes are caused by too high of tire inflation (so the issue may not be wide tires, but rather over inflation).
A little lower pressure and larger contact patch may help. Perhaps the benefits are non-linear. 28mm? 32mm? 70 psi?
One issue that has been mentioned is that a wide tire mounted on a narrow rim will tend to flex to the side a bit, which may be problematic, so one should choose a decent matching rim and tire.
