Tire pressure
Are you guys experiencing issues with your tire pressure? When I got my GS, it had 33 tire pressure all around which I believe is the manufacturer recommended tire pressure. One week later, I noticed it dropped to 30 so I had to add more air. Another week later, the tire pressure is down to 31 again so I have to pump air again.

Pressure fluctuates when the outside temp changes and when your tires heat up from driving. The colder the tires, the lower the pressure will be. Only pay attention to the pressure when the car has been sitting overnight. As long as it never drops below what the door placard says, you're fine.
Also always inflate your tires when they are coldest. Like late at night after the car has been sitting for a few hours or first thing in the morning after the car has been sitting overnight.

I find that, on these lower profile tires, tire pressure is something to be maintained, rather than "set and forget". There are always fluctuations due to temperature changes and normal losses, and those seem to be more pronounced on low profile tires.

As part of their prep my dealer uses nitrogen to fill the tires. I have to say even in the Canadian cold of winter the pressure fluctuation is not a problem. You might try it out. I know there was no extra charge, it wouldn't hurt to ask them.

Deflate and refill with Nitrogen...it holds better and less fluctuation than regular air. I set mine to 40psi on the stock F-sport wheels...and if it's cold outside..it came down to 37psi...
