A screw punctured my tire last week, and because I did not drive the car for a few days, the tire pressure dropped to 90 kPa.
Since the car tire pressure sensor only kicks in after a while, we realized this after driving out onto the main road. Luckily, our tires are run-flat, so it is relatively safe to drive to the nearest petrol station and fill it back up to 220 kPa.
