Correct answer
- BAsegurarse de que la profundidad del dibujo de los neumáticos nunca sea inferior a 1,6 mm.Make sure the tread depth of the tyres is never less than 1.6 mm.
Explanation
Grip depends largely on the tyre tread, which clears away water; its depth must not be less than 1.6 mm on cars (Annex VII of the General Vehicle Regulations). Inflating above the recommended pressure reduces the contact area and grip.
