Got a new car.

First brand new car I ever bought. Still unsure about that. Anyway.

It has the nitrogen filled tires.

Thoughts?

I think most cars are coming like that. My wife's car is like that. Since we still get it serviced at the dealership they just top it off there. However, if you need to inflate your tires a bit, you can still fill them with air until you get to a service facility that provides nitrogen.

Beyond that, I have no idea what the benefits are.

Oh, and one other thing, the major reason you may have had to top off your tires between servicing with air in the past has been because of temperature changes. Nitrogen by its nature doesn't leak like air.

All new cars are filled with nitrogen, it doesn't contract and expand with temp as much as air does so your tire pressure from summer to winter fluctuates less. We got my wife a new pathfinder last fall, also first new car I bought as well and hers had nitrogen in the tires.

Nitrogen tires will still be affected the same by ambient temperature changes. The ideal gas law says they will still contract and expand with temperature changes. 1.9% for every 10 degrees F to be exact. There will only be less fluctuation while driving due to less water vapor.

The only real advantage is that less nitrogen will leak from the tire than regular air. Is that worth the money? Depends on the driver.

Well of course it will still contract and expand, it's still a gas after all.

And for everyone knocking on nitrogen filled tires, it's not as if you're paying any extra for them when you buy a vehicle, if it doesn't matter to you just put air in it when it needs it, doesn't hurt anything.

Air is roughly 79% nitrogen already... why pay for the extra 21%? The whole idea is a waste of money...makes no cents to me.

Nitrogen is overrated. Just keep a reliable gauge in the glovebox and check your tire pressure once a month. Problem solved at a fraction of the cost.

Nitrogen filled tires are drier inside than regular air filled tires, Compressor heating up the air then it cooling condenses. Really little benefit... But then again I've only been in the biz for 35+ years. Only real benefit is in high end racing (read NASCAR) where pressure changes as little as 1/2 psi makes a difference.
