The best way to check what size inner tube you need is to look on the sidewall of your tyre. Tyre manufacturers print the size on the sidewalls, so look out for numbers such as ‘700x23c’ for a road bike, or ’26×1. 75′ which is for mountain bikes.
How do I know my bike tube size?
The first number is the diameter of your wheel. Sizes such as 26, 24, 20, 27.5, 29 and 700c are common tire diameters. The second number (after the X) is the width of your tire. The range for widths is usually between 1 and 3 inches.
What size inner tube do I need for 700x32c?
Just like balloons, the dimensions of inner tubes vary with the volume of air that you put into them. So you’ll find that tubes are labeled with the diameter and a width range, e.g. “700×28-32”. In that case, a tube with the size 700×28-35 would be great for tires from 700×28 right up to, and including, 700×35.
Is the inner tube the same size as the TYRE?

What are bike tire sizes?
Generally, bike tire sizes are indicated with two numbers that correspond roughly to the outside diameter of the tire and the width of the tire. These would usually be measured in inches (26″, 27″, etc.) or millimeters (650, 700, etc.).
Can I use a smaller inner tube?
Yes, you can, as long as you don’t go more than one size smaller, or the differential is not too extreme. A 1.25 in a 1.5 is fine. A 1.25 in a 2.25 is likely to have issues with flats. Your LBS will have tubes.
