Last week, when I picked up the 991.2 turbo (2016 year, checkbook, etc.) from the garage, the tyre pressure loss warning came forward with the indication that the front right (and only there) -0.5 bar was available for the nominal pressure. The car had been standing 3 weeks ago. The control at the gas station showed that the display was correct. I filled up the missing 0.5 bar and since then I have constantly observed the air pressure during the ride via the multifunctional display. last Wednesday and I have since driven about 200 km, highway, city traffic and highway (with max. 200 km/h). Result: No more pressure changes compared to the other tires, i.e. the same cold values and the same pressure increase when driving by 0.2 to 0.3 bar. ? Does anyone have an idea what was / is going on? It is well known that a tire, rim or valve cannot repair itself. I wait until MItte next week (without driving), and if the tire then a In the meantime, I would be grateful for every tip, especially if there is no further change. The rim and tyres are in an optically flawless condition. The summer rims are the original Porsche Turbo wheels (part number 991 044 601 52) and were purchased and assembled together with new tyres at the PZ in spring 2019. In November 2019, the winter bikes came on top and in April 2020 the summer bikes, i.e. those on whose wheel of the pressure compartment All works were carried out in the PZ. Greetings rab2
