Tires and different sizes
To date, there are various indications and methods for establishing the measurements of the various tire models. Among the main and most used we find: ETRTO - INCHES and MILLIMETERS.

• ETRTO: all bicycle tire sizes are indicated according to ETRTO standards (European Tire and Rim Technical Organization - European technical organization for tires and rims). The ETRTO measurement indicates the width and internal diameter of the tire, both expressed in millimeters.
• INCH: specifies the Outside Diameter and Width of the tire, both expressed in inches.
• MILLIMETERS: specifies the External Diameter and the Width of the tire, both expressed in millimeters.

Below is an example of different units of measurement with the example of a 24 × 1 tire (25-540).
