Tire pressure with Nitrogen
Hello, just noticed a discrepancy between the door sticker and TPMS readings; 36PSI for the door sticker and 47PSI on the TPMS. A long story short, measured with a gauge and the TPMS readings are accurate sent a message to my dealer because I took delivery of the car 10 days ago, no answer...
I understand those tires are filled with Nitrogen, are the original values (47PSI) a requirement for Nitrogen or should I deflate those tires to door stickers values ?
Thanks in advance.

Don't quote me on this but I believe that the factory will over inflate the tires just incase the car will be sitting on a lot for an extended time. The dealership should have done an inspection before delivering the vehicle to you with the correct tire pressure.
So to answer your question; Yes, absolute set the tire pressure to the correct 36 PSI.

I agree with the other comment about dealerships frequently over inflating tire pressure. That's been my experience in the past. Either way, I wouldn't worry about it. Just adjust the pressure as needed.
Also, make sure to check your tire pressure in the morning before you drive the car to get an accurate reading of the cold tire pressure. Your tire pressure will increase when the tires warm up from driving.

Thank you all for your replies, I have to say that I am very disappointed of my Lexus Dealer I had dealt with, contrary to my previous experience with a BMW dealer, where everything was checked and double checked in front of me. I have already adjusted the PSI of my tires as to the sticker.
This forum is priceless!
