I'm sure this has been asked just about a million times, but I haven't come up with a good answer anywhere. My latest project came with the original set of Schwinn Westwind tires and Schwinn Approved tubes, but they are pretty much rotted through. The thought of NOS tires is appealing, but I'd rather not spend more on replacing the tires than the whole rest of the bike! Is their any decent aftermarket 26 x 1 3/4 tires available on the market today? Anything made in the states? I've used some Chinese made tires in the past and they, were to say the least, junk.
