First and foremost, you want to make sure the tube fits your tire. To determine the size you need to check the side wall markings on your tire where you’ll see two numbers separated by an 'X'. The first number refers to the tire’s diameter. The second number refers to the tires width. Select the tube that has the exact same diameter as your tire. Your tires width should fall into the range of widths listed on the tube packaging.
