## What size inner tube do I need for a 700x40c?

Here it is: pick a tube that matches the numbers embossed on your tire (i.e. “700x40c”). The size of an inner tube varies with the amount of air that you fill them with. So, they’re sold by fixed diameter and range of widths e.g. “ 700×35-43” (which would work for tires ranging from 700x35c to 700x43c).

## How do I know what inner tube I need?

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.
