Tannus Armour Size Guide

When you use Tannus Armour with an inner tube you need to use a slightly smaller tube than the size listed on the side of your tyre. The table below is a list of Armour sizes and the recommended inner tube size.

Important information if you are supplying your own inner tubes

If you already have inner tubes to use with your Armour inserts please check the table to make sure they are the correct size. Where a range of sizes is shown we always recommend that you use a tube at the smaller end of the range.
