Example: P205/55R16 91H


Description:


P: Indicates a passenger car tyre (not always used; some tyres may omit this).


205: Section width in mm.


55: Aspect ratio (height of sidewall as a percentage of section width).


R: Indicates radial construction.


16: Rim diameter in inches.


91: Load index.


H: Speed rating.




2. Metric Format (without P)


Example: 205/55R16 91H


Description: Similar to the P-Metric format but without the P. It’s commonly used for various vehicles, including light trucks and SUVs.



3. European Tyre and Rim Technical Organization (ETRTO) Format


Example: 205/55R16 91H


Description: This format is similar to the metric format and is often used in Europe. It specifies section width, aspect ratio, construction type, rim diameter, load index, and speed rating without the P designation.



4. LT-Metric Format (Light Truck)


Example: LT235/75R15 104S


Description:


LT: Indicates a light truck tyre.


235: Section width in mm.

12: Rim diameter in inches.


This format often omits load index and speed rating.




8. Scooter and Motorcycle Tyre Format


Example: 80/100-18 M/C 48P


Description:


80: Section width in mm.


100: Aspect ratio (height equal to the section width).


18: Rim diameter in inches.


M/C: Indicates motorcycle.
