My Cruze tires are supposed to be filled with Nitrogen. The dealer did it, not I. So the theroy is the nitrogen is supposed to be more stable for the PSI. I am running with the theroy to see if it really works in this case.

So far I haven't found it to be so. Where I live temps range 40 degrees from morning till evening, daily. The dealer set the tires at 37 PSI a month ago. They were at 34-35 this morning. Is it temperature that is the issue, making it really just a crock of bull? Or is there a possibility of a leak?

Over all temps have dropped 20 degrees for the season.

At the atmospheric pressures and temperatures a typical passenger car deals with there is no difference between nitrogen and air when it comes to temperature related tire pressure changes.
