What brand tires are those?Then, I don't recommend any of the tires mentioned above. If you want to keep the original rims, the best tires that I have found that are close to the original tire size, 1 1/2" or 38mm is modern sew up cyclo cross tires. They don't look as authentic as the reproduction tires, but they are the best that I have found. THe reproduction tires are far too heavy.
