Check tyre pressure regularly
In order to stay safe on the road, you should make sure that your tyres stay properly inflated. Remember that this is the only element of your car responsible for acceleration and braking, that interfaces the road. If this contact is less than optimal, there is no way to drive safely.
If your car does not feature tyre pressure gauges built-in, you should check it manually once a month. Also, every now and then between the measurements, have a quick walk around the car to visually inspect if there’s no big pressure drop in any of the wheels.
