Anyone fill their tires up with Nitrogen?

The dealer said they fill the tires up with Nitrogen, not sure where I can get this done at other than the dealer. I like to check the tire pressure pretty regularly and dont want to run to the dealer every time the pressure goes down a bit. Obviously I could just use regular old air but nitrogen doesnt fluctuate as much with the heat and the cold.

My wife has it in her 300C and she says it makes a big difference. I can't tell but she says it rides softer...

It's all COSTCO uses in their shops. Most other shops have it now, but some charge a premium. 34PSI is 34PSI, shouldn't affect the ride, but it sure makes a difference in fluctuation. Best used where you have big day/night temp swings. Big deal up North, not so much here in FL. Had nitrogen in the Bimmer, and not the Genesis, and can't tell the difference.

thanks for the info guys. I was also curious for my GS because I keep it around 39psi for the low profile tires, and nitrogen would be perfect
