Measuring Instructions

  1. Measure the diameter of the existing tire, as illustrated above (D), or look on the tire for the size (it looks like this: nn" x n.n").
  2. If you find the tire size, the first dimension is the tire diameter, the second dimension is the tire thickness.
  3. Record the tire diameter, as this also represents the bike frame size.
  4. Select your bike size from the drop-down on the right to see a rider chart.
