## Tyre Speed Ratings

### Tyre Speed Symbols & Categories

Most car and van tyres used in the UK have both a load and speed rating after the tyre size, e.g. 195/65R15 is usually followed by 91V. This means the tyres can carry their rated load upto a maximum non-stop speed of 240 kph. When replacing tyres it is important to ensure the new tyres, even if a different size, have the same or a higher speed rating. However, in the UK, with a national speed limit of 70 mph, it is quite safe and not illegal to fit a tyre with a lower speed rating. The table below shows the maximum speeds applicable to each speed letter.
