|F|| 80 km/h||A letter in the tyre code encodes the maximum speed of a tyre. Thereby, the table has been expanded downwards from the earlier for 180 km/h valid letter 'S' (speed). Upwards was more difficult because the letters 'H' (High speed) were pre-defined for 210 km/h maximum and 'V' (Very High speed) for speeds of more than 210 km/h. Moreover, the table had to be extended due to the speed increase of standard cars.|
Mud-snow-tyres can not always reach these high speeds. Nevertheless, they may be mounted if an appropriate marker is placed in view of the driver.
