Well considering that hybrids are already heavy......
Probably doesn't matter on hybrids, because at a certain speed wind resistance becomes the limiting factor. So it really isn't about speed but a required wattage.
Speaking of watts, a 25c clincher tire ranges from a rolling resistance 9.9 watts (Continental GP TT) to 21.9 watts (Schwalbe Lugano). I'd rather ride my hybrid on a 35c Nomad Resist than a 25c Schwalbe Lugano.
