So besides greater risk of flats, you are creating a much harder, less efficient ride.

The only time my tires aren't at 115 or 135-140(tubulars) is if I am at a crit with bad road conditions in the turns. Then I know I am going to need to let some air out. Otherwise, if just riding on paved roads- there is no reason to have them underinflated.
Not everyone agrees with this view.
