well, i can take 25 pounds, thats how much mine wieghs right now, i was thinking they came lighter, and i love skinny tires on my commuter, 700x23 has been working for me great, just one flat after 2000 miles, i dont go off of curbs really, i have a nice bike trail next to my house and both my jobs and school are all right next to the bike trail, so i dont need big tires or something that most people have as a commuter
