Correct answer

It is important to check tyre pressure at least once or twice a month. We will do it when the tyres are cold, keeping to the pressures recommended by the manufacturer. Bear in mind that a tyre with the wrong pressure wears unevenly, has a higher risk of a blowout and can increase fuel consumption. * With a pressure lower than the manufacturer's: - They wear more at the edges. - They flex and heat up more. - The risk of a blowout increases. - Grip is reduced and the risk of aquaplaning increases (the tyres cannot clear the layer of water on the road and lose grip). - Fuel consumption increases. * With a pressure higher than the manufacturer's: - They wear more in the centre. - The area of contact with the road and grip are reduced. - They do not absorb bumps in the road well (they vibrate more and the suspension wears).
