What is the ETRTO size? The ETRTO size is a standardization developed by the European Tyre and Rim Technical Organisation. It allows easy verification of whether a new tire will fit your bicycle.

The ETRTO is written in a format similar to postal codes – e.g.: 47-355. What do these numbers mean?

• 47 mm – is the tire width,
• 355 mm – is the tire's internal diameter, that is, the rim size the tire must fit.

Note: The diameter (second number) must match your current tire – this cannot be changed. However, the width (first number) can vary – you can choose a narrower or wider tire as long as it fits your bike frame.

To be sure you are buying the right tire, look for the ETRTO marking on your current tire and choose a new one based on the same code (at least the second number).
