You asked: What size of bike tire tube do I need?

How do I find the size of my tire tube?

The size is almost always written somewhere on the sidewall of the tyre. Inner tubes typically state a wheel diameter and width range for which they will work, e.g. 26 x 1.95-2.125″, indicating that the tube is intended to fit a 26 inch tyre with a width of between 1.95 inches and 2.125 inches.
