Flat tires suck, I hate to spend what little I get to ride on the side of the road.
I'm running Gator-Skins, 700x28, and they aren't flat-proof. Nice tires, but
really can't say I get less flats with them.
I've decided no one makes a flat-proof tire. I guess it's the weight-weinie in all of us that keeps tires light and vulnerable.
