Here is a more complete list of specification definitions commonly found on the sidewalls of a tire:

1. Tire size: Represents the width, profile and diameter of the rim, expressed in millimeters and inches. For example, "225/50R17" indicates a width of 225 mm, 50% profile, and a diameter of 17 inches.

2. Load Index: A number that indicates the maximum load capacity that the tire can safely support. This number varies and corresponds to a specific load in kilograms or pounds.

3. Speed ​​index: Represented by a letter, it indicates the maximum speed at which the tire can operate safely. Each letter is associated with a specific speed, although the exact value may vary depending on the standard used.

4. Tire construction: It can be "Radial" or "Diagonal". Radial tires are the most common and are constructed with layers of radial cords that extend from the bead to the sidewall of the tire. Bias tires have angled diagonal cord plies.

5. Technology or special features: Some tires may have additional terms to describe specific features, such as:

- Run-Flat: Indicates that the tire is capable of running temporarily without air after a puncture.
- Tubeless: Means that the tire is designed to operate without an internal air chamber.
- M+S: Indicates that the tire has a tread design suitable for mud and snow conditions.
- XL (Extra Load): Indicates that the tire has a reinforced load capacity compared to the standard.

These are the main specifications found on the sidewalls of the tires. However, it is important to note that some tires may have additional information or manufacturer-specific terms that may provide details about the tire's technology, performance, or recommended use.
