I have read quite a bit trying to find the perfect tire. There isn't one. I had similar thoughts but didn't like the idea of toting a tire, but maybe that isn't such a bad idea. My first impression of shinko's were.. well cheap. And they were 3-4 years ago, but quality has improve since then according to the reviews. The 700s do look good. Ever try using the kickstand of a buddies bike to break a bead? Just insert your tire and lean the spare bike over (with someone on the bike).
