Thanks everyone, I did go out and get the continental unltra gatorskins 700 x 23 c -- however, I am having a hell of a time trying to get it on the bloody wheel. Finally, I got it on but then I managed to puncture the inner tube in the process. Any advice on how to do this? Also, I was thinking maybe the 23c is a little too narrow - do you think the 28c would be better for riding around in the city. This is not a racing bike it is an altered bike with upright handlebars, although it still has the Shimano 600 and everything else on it that would make it a racing bike. Oh, and getting the old tires off was a *****! I had to cut through steel, because of course as a newbie I messed up trying to get the tire off. The second one went easier. The tires on it originally were Specialized Touring 700 x 28C. Any help would be appreciated.
