OK, I am confused (again) I guess.
I have heard people discussing the inaccuracies of tire pressure monitoring systems. I have no previous first hand experience with them but I am dealing with my wife's 2017 Macan.
This is the sticker on her Macan. It says 36 front and 39 rear as you can see. The display on the dash says it has 30 front and 34 rear. The right front tire showed a low pressure so I added 1 PSI to it to get it to 34. According to my tire pressure gauge it is now at 34 front and 37 rear and that is what is likes to see.
So do I have to just "sneak" up on it with guesses to keep it happy?
Within a month of having the car the front left tire warning came on and according to my gauge it was identical to the other side tire. I mean dead on the same. I had her swing by the dealer and they claim they added two PSI and it was happy. They did not even try to charge anything since we bought the car there.
And as a technical note the tire pressure gauge I use is a dial type gauge labeled a "Accu-Gage" and it reads the same as the other dial gauge I use.
