Hey all! New to the thread/new audi owner.

I bought an old fashioned non digital tire gage yesterday and checked all 4 tires. All came in at 35-36 PSI. the MMI has not yet been set to detect tire pressure as it is asking me to say whether or not they are filled correctly before it does. 35 is too low correct?

I checked the book and it seems 41 psi in front 2 and 39 psi in back two.. is this the same for Nitrogen?
Also, the car came filled with Nitrogen, is it worth it to keep this moving forward? I have a costco membership and have been told I can fill there for free.. If so its about 10 miles from my house, but I need to head there a few times a year anyhow.

Thanks everyone!

41 is the PSI you use if your car is full of passengers all the time. If not, check the manual for the PSI under normal loads (can't remember what it is off the top of my head, I use 39f-36r.).

Yes, use same PSI for nitrogen.

FYI. Air is over 70% nitrogen. I run 39 psi front and back. Mixture of oxygen, nitrogen, CO2, and other gasses.

If run flats they produce an uncomfortable ride. It's the sidewalls. Stiff. Too stiff for me.
