When reading the 120/70-17 motorcycle tires code, it conveys the following information. The section width from left to right in millimeters is 120, and that’s where the rubber mets the road. The aspect ratio of that first number is 70 percent, which is the general “height” of the sidewall. The 17 in this case is rim diameter, which isn’t measured from outer edge to outer edge. You need to measure from where the tire bead will sit inside the rim for an accurate size, which should also include pulling the wheel and current tire off the rim.
