What kind of bike do you ride?
I use Mountain wheels with Continental Gatorskins about 1.2inches I think. Not great for grip at the mo, though great in the summer. They have virtually zero rolling resistance and really make a difference to the commute time. You can only use these on road though, so you need 2 sets of tyres, one for off road aswell. Not had a puncture with these yet in a year and 3 thousand road miles. I had loads with my last set of conti sport contact. Hope this helps.
