Tire Diameter: The most crucial measurement is the diameter of your tire. It’s usually indicated on the sidewall of the tire and can be expressed in inches (e.g., 26″, 27.5″, 700c) or millimeters (e.g., 650b, 622).

Tire Width: In addition to diameter, pay attention to the width of your tire. The inner tube size chart often accounts for different tire widths within the same diameter range.

Valve Type: Inner tubes come with different valve types—Schrader or Presta. Ensure that the inner tube’s valve matches your rim’s valve hole.
