Si conduce una motocicleta y la calzada está mojada, ¿es necesario incrementar la presión de inflado de los neumáticos por encima de la recomendada por el fabricante?
If you are riding a motorcycle and the road surface is wet, do you need to increase the tyre pressure above the one recommended by the manufacturer?
- ANo, ya que una mayor presión de inflado no contribuye a aumentar la seguridad de circulación.No, because a higher tyre pressure does not make riding any safer.
- BSí, porque aumenta la adherencia de los neumáticos y mejorará la seguridad de circulación.Yes, because it increases tyre grip and will make riding safer.
- CSí, ya que aumenta la seguridad de circulación y así se evitan los derrapes.Yes, because it makes riding safer and prevents skids.

Correct answer
- ANo, ya que una mayor presión de inflado no contribuye a aumentar la seguridad de circulación.No, because a higher tyre pressure does not make riding any safer.
Explanation
The correct pressure is always the one recommended by the manufacturer. Over-inflating reduces the contact area between the tyre and the road surface, so it does not improve grip or safety, not even on a wet road.
