I'm curious, how is it done? A precise measure would be if there were a sensor inside the tire however that seems unlikely as people use 3rd party rims and tires and I assume people rotate/replace the tires at home or have a local grease monkey do it. Here in Estonia we need to swap out the tires twice a year anyway because we need real winter tires for the Nov-Mar timeframe so that's also the time we get them rotated. I'm just wondering how can Tesla measure the pressure accurately without a sensor in there. So tech educate me
