Specific questions & reccomendations on tires
 

I've been out of the sport of cycling for a long time, so there is still a lot of product info that I need to rediscover. Right now I'm looking for a good set of "urban cyclocross" tires as I call them. Currently I'm riding a pair of Specialized Infinitys on the road (700 x 32). They are bombproof and heavy, which is fine, but they are also super-hard to get on and off the rim which means that I fear getting a flat with these in a way that I don't with my folding cyclocross tires. While I switch to proper cyclocross tires for the nasty weather and off-roading, I use my "urban cyclocross" tires for exploring and destroying the roads, paths, bridges, alleys, and sidewalks of New York City.

Here's what I'm looking for to use on the Gipiemme rims of my Cannondale Cyclocross. Can anybody suggest a tire that meets these standards or features:

- 700 x 28c or 700 x 32c
- Folding, kevlar bead, or any clincher that is reletively easy to mount and remove from the rim
- Treaded enough for dirt, sand, gravel, and other common road debris, yet conservative enough for cruising along on smooth asphalt
- A degree of built-in flat proofing

Many thanks in advance to everybody who responds.

I love my Bontrager Xlite Race 700 X 28, which have kevlar bead and belt, but also super light and low rolling resistance. They have zero tread which is the perfect amount for everything except snow and soft sand. They are made of some silicon compound so they may not grip in the wet but I havent noticed it. I have had no trouble getting them on and off the wheel.

A great tire that I used in Europe this summer is the Continental Top Tour 2000. Streets, bike paths, cobbles and gravel didn't seem to faze the tire. It handles well, offers good grip under all the conditions I rode in and didn't have any flats. It comes in both 28 and 32 widths, but unless you're carting around a big load, the 28 inflated around 85~95psi would work just dandy.
