I forgot about retreading. Yes, it was a thing for passenger cars in 1950..1980 in Spain (guessing the range). > > Theoretically you're supposed to check the inflation daily but with 18 > tires the common practice is to 'thump' them.

My current car has pressure sensors on the 4 wheels. I can read the values in the dash display. I think the sensor is in the valve, with a battery and a radio. Two weeks ago I was driving a courtesy car while my car was in the garage: same type of car, an Opel Corsa, but newer. It doesn't measure the pressure; instead it alerts you of low pressure. It actually activated one night, and I had to go to a station to fill air. The meter there said 1.8 or 1.9 Kg/cm². Minimum rated was 2.2, max close to 3. So I inflated to 2.5, same as my car. Once inflated, you press a button to reset the sensors. I prefer the system in my car. I think some system of the sort is currently mandatory in the EU. -- Cheers, Carlos. ES🇪🇸, EU🇪🇺;
