Show answer

Correct answer

  • B1,6 milímetros1.6 millimetres
Explanation

The Traffic Regulations say that the minimum depth of a tyre tread is 1.6 millimetres, although it is advisable for it to be above 2 millimetres. Below 1.6 millimetres you will be driving without any safety, because the tyre will not grip the road surface properly.
