For the vehicle to grip the road well, what must you do?

A)Use radial tyres on the front wheels and diagonal ones on the rear.
B)Make sure the depth of the tyre tread is never less than 1.6 mm.Correct
C)Inflate the tyres more.
We must periodically check that the tyre tread is still above the wear indicators; otherwise, the vehicle will have less stability on the road, will travel more metres when braking and the risk of losing control of the vehicle when driving on wet pavement will increase.
A depth of at least 2 millimetres is recommended; 1.6 mm is mandatory.
