Check the tyre pressure

A tyre, even a new one, looses 0.15 bars of pressure each month. If tyre pressure is too low, this increases fuel consumption and influences road control and handling. Check your car’s tyre pressure monthly. Driving increases tyre pressure because it warms and expands the air inside the tyres, so be sure to check your tyres when they are cold (i.e. when you have driven less than three kilometers) to make sure that your pressure reading is accurate.
