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. :cool:

Conti Grand Prix 4000's have been a godsend for me! Living in the desert we have lots of "pokey things". I've had 2 flats in three + years.

I have Continental Grand Prix 4 Season tires (700x25) and am very impressed with them. Can't believe the sharp jagged rocks I've had to go over a lot lately and they didn't even blink. The streets of our town are being torn up and sewer pipes replaced everywhere, and Boy it's a nightmare of nasty sharp rocks and debris scattered so thick on the street you cannot dodge them- you just cringe and pray and go over it. Rocky gravel would be better since your tire could sink into it a bit. I hate it when you catch just the edge of a sharp rock and it gets shot out from the side of your tire like a bullet with a creepy snapping sound like a slingshot. Aghhhh!! :eek: :( But these Continentals are seemingly taking it all in stride.
