Hi,
you need to pick a tire size, or weight, and then choose from within that group. If you don't get sidewall cuts where you live, I'd go with a traditional sidewall, the ride is much nicer. I like to run as light a tire as I can, with the goal of having not more than one flat a year. I usually get a flat in the spring,replace the tires, and then run the rest of the year without incident. I use Rivendell Ruffy Tuffy tires, 27c, about 350 grams. They're not light, but they aren't heavy either. And they are quire reliable where I live.
