Correct answer

  • BEl vehículo tendrá menor adherencia.The vehicle will have less grip.
Explanation

Tyre pressure must always be the one recommended by the manufacturer. When the pressure is HIGHER than recommended: - The contact area with the road is smaller, and so is the grip. - The tyres wear more in the centre of the tread. - The vehicle absorbs bumps in the road less well. When the pressure is LOWER than recommended: - Grip is reduced. - The tyres wear more at the sides of the tread. - Fuel consumption increases.
