ok sorry, total noob. here are some pics of the tires. i am going to do triathlons. also, the sizes are 700x20 and i wonder if that is a little narrow, maybe go with 700x23 which seems to be somewhat common?

When you replace them, get some 23mm wide tires. They won't add any additional rolling resistance, and they'll give you a more comfortable ride than the 20s .
