I found these on Amazon for $19.99 w/free shipping over $35. Is anybody running this tire? It is advertised at 2.125 width, but the sidewall looks tall so they would probably be wider in that area according to the rim they were on. I think that they appear a little like a pie-cut slick on the sidewall, the design is what is drawing me to them. Any idea of the manufacturer? The ad says Schwinn?
