Has anyone replaced the "air" in the tires with nitrogen, I was wondering if this would stop the need to fill the tires during cold weather. I have a price of $199 usd. That seems to be the going rate. My wife just purchased a new Honda pilot and the dealer offered it and the car has not had the low pressure light go on. Here in NJ the past two weeks it's been around 10 to 15 degrees. Yes cold but on the up side that darn auto stop/start has not come on.
