Correct answer

  • BPresión de neumáticos excesiva.Tyre pressure too high.
Explanation

If the tyres show wear in the centre of the tread, the most likely cause is tyre pressure that is too high. When the pressure is too high, the centre of the tread carries more load than the edges, so it wears more in the centre. This uneven wear can harm the tyres' performance and shorten their life. So it is important to keep the tyre pressure within the range recommended by the vehicle manufacturer, so that the tread wears evenly and the vehicle is as safe and efficient as possible.
