The wheels on my mountain bike are 26x1.5 to 26x(something over 2). I bought the thinnest tire I could that fits this frame (26x1.5) and ordered tubes of the same size. For some reason the tubes have a slightly larger diameter than my tires. Is there a reason for this? I currently have slicks that are 1.90 with tubes to match and those work and fit just fine. For some reason I'm having problems getting the 1.5s to match up. Any thoughts?
