Show answer

Correct answer

  • ACircular con una presión de inflado muy inferior a la recomendada por el fabricante.Driving with a tyre pressure far below the one recommended by the manufacturer.
Explanation

Driving with a pressure far below the recommended one makes the tyre flex, heat up and wear out faster, especially at the sides, as well as increasing fuel consumption and reducing stability. Driving at a moderate speed and with the correct pressure makes tyres last longer.
