Who has switched to nitrogen for tires?

[Darwood77]

Does anyone bother doing this anymore, or is it not worth the time and expense. Discuss!

Air is like 78% nitrogen so I'm not sure what the point of that would be...

I've been using unicorn farts for years. The Greenlandian unicorn product is the best.

Costco included nitrogen fill with new tires.

I would NOT pay extra for it.

I work for a company that sells nitrogen and other atmospheric gases and I use it. The main things I have noticed is less variance in my cold and hot tire pressures.

A co-worker who also uses it in his tires stated that Nitrogen tends to not migrate through the rubber of the tires as quickly as Oxygen and compressed Nitrogen also has much less water vapor.

I probably will go back to straight air when I am no longer able to get nitrogen at work.

As DirtyT3sla states, air is 78% Ni.

I really like your YouTube channel, btw.

The current set of tires on our other car came from Costco, but I have a air compressor at home and top it off with it because it is more convenient.

In normal use, and for free, it is objectively, very very very marginally better than "air"- so sure.

For anything other than free that marginal amount isn't worth whatever your cost is.

And I figure if it’s the 22% other stuff leaking out - the in tire nitrogen content will always be increasing!

Exactly 78%, my tire shop guaranteed me. They said I don't need more than that.

The supposed point of using nitrogen in your tires is that it is not as variant in volume with temperature, so if you inflate your tires to 45 PSI with nitrogen when it's 45 degrees Centigrade out (hi from Phoenix!), the tire pressure won't go down as much when it gets down to twenty degrees.

But since we have TPMS in modern cars, it's not as "necessary" anymore (not that, in my opinion, it ever was), it's mooted by the car letting you know when your tire pressure has changed on you.

Waste of money. Also consider the tire already has air in it, its not like they evacuate the normal air and only pump in nitrogen.

 

[DopeGhoti]

Waste of money.

Most places that I've seen do not charge to do this.

78% nitrogen for me

There are some benefits of pure nitrogen in racing but zero benefits for a road car

The Ideal Gas Law has not been repealed for nitrogen — there should be no difference at all in pressure variation with temp from nitrogen/oxygen mix. Presumably the advantage is therefore either in pushing out the water vapor or preventing the reactive oxygen from messing around in there?

Required markup/purchase on my moms BMW X3. Dealer already added. Rip off. It was $75 per tire. Non-negotiable. .

I'm breathing nickel?

Doesn't anyone make a nitrogen pump? It filters out all the other gases in the atmosphere and only pumps nitrogen.

Everything is negotiable.

that being said that’s such a shady tactic to increase their bottom line.
