Correct answer

  • CQue la presión de inflado sea superior a la correcta.A tyre pressure higher than the correct one.
Explanation

If a tyre wears more in the centre than at the edges, the usual reason is that its pressure is higher than the correct one: the centre of the tread bulges and carries almost all the load. With low pressure the opposite happens: the edges wear.
