Show answer

Correct answer

  • ACon los neumáticos fríos.With the tyres cold.
Explanation

Pressure is measured with the tyres cold, that is, before driving or after only a few kilometres. As you drive, the air warms up and the pressure rises, so measuring it hot gives a false reading and would lead you to let air out until the tyres are below the recommended pressure.
