Correct answer
- BPresión excesiva en los neumáticos.Too much pressure in the tyres.
The correct answer is too much tyre pressure. According to the rules, significant wear in the centre of the tread shows that the tyre pressure is too high. This happens because when tyres are over-inflated, the contact area with the ground is reduced, which causes more wear in the centre of the tyre. This not only shortens the life of the tyre but can also put the vehicle's safety at risk, because it affects grip and handling. This is linked to the minimum requirements for tyre use set out in the Traffic and Road Safety Code.
