Correct answer

  • ASí, porque el vehículo puede derrapar por falta de agarre.Yes, because the vehicle may skid due to lack of grip.
Explanation

Aged, hardened rubber loses elasticity and grip on the road surface, in both dry and wet conditions: the vehicle may skid and the braking distance increases. That is why tyres should be checked even if they have enough tread.
