AWD , running at 35psi cold. Just like they said so in the door. When I got the car warm they always ran 38+ so I lowered it. Like I said, never had a car with real time monitoring. I also understand temperature via the seasons has much to do with it.
I was used to my BMW’s staggered running 32 up front and 35 in the rear due to size difference My oversight.
This thread offers nothing new BTW. I have read this before but ignored it. Read a few posts complaining about MPG and was not thrilled with mine either. Engine usually starts to improve at or around 5k, and I reset my monitor then. With gas prices rising and my driving more back to precovid days I thought I’d at least revisit this.

 

That's what I run as well, 35PSI cold.

 

This would make the car a lot lighter and almost make it float which would increase MPG right? Cornering would be tough though. You'd also have the issue of coming out every morning to your tires being half deflated - but yes...they probably would sound funnier especially when they squeal.

On a more serious note....I was talking to one of the tire shop guys a long time ago about not liking how a certain set of tired handled. He mentioned going a tad bit higher on the pressure, I think it was about 3 PSI and it definitely made a difference. I'm still playing with the GS and figuring out what I like so I don't know that I have a good sense of things but maybe I'll set them a little higher this winter.
