Decoding a tyre size code

    • Tyre width: The first number in the code – 185 – denotes that particular unit's width in millimetres.
    • Aspect ratio: The number 55 indicates the aspect ratio, which is basically a measure of the tyre's sidewall divided by its width in percentage.
    • Radial: 'R' signifies that this particular unit has a radial construction. Most tyres available today in the UK are of radial type.
    • Rim diameter: The next number – 16 – denotes the recommended rim diameter.
    • Load-bearing capacity: 83 refers to the load-bearing capacity of each unit when fully inflated.
    • Speed rating: The last letter in the code – V – stands for the tyre's speed rating.

Apart from these basic metrics, the following parameters may also be mentioned in a tyre size code.

    • E marks: E marks are official proof of a tyre's adherence to the protocols laid down on the ECE Regulation 30-02.
