Dry nitrogen is used to purge aircraft pitot static systems and due to non flammability is used in aircraft tires. Nitrogen used for tires at our level is a joke. I'm a nobody but JMO.

If it makes you feel secure and all fuzzy inside, then go for it. Who cares? Or you can invest in a pet rock.

I have several for sale. They are house trained and very well behaved. Perfect camping companion. They don't bark when you're away or chew things up. Pics available upon request. Cash payments only.

Nitro will not heat up and expand (like "wet" air) altering tire pressures between hot and cold so much, The NASCAR types use it due to their very slight suspension adjustments via 1/2 lb of "air" pressure in their tires.

air is ok by me for tires, as long as they are checked cold and often.

Nitrogen. Yes or no

I work for a company that makes mining equipment. They don't go 200 MPH or land on an airstrip, but yet they're filled with Nitrogen because it's stable throughout temp variations, working at steel mills etc.

Yes to Nitrogen.

This can be debated from now until eternity and those that like it will never change their minds as will the non-users never change their minds. Unless you are going over 200 mph or higher than 20,000 ft in your camper, you are wasting your time and money on the nitrogen. Just a fact of life folks.
78% nitrogen is close enough.

I would love to see the source of this assertion. (Just sayin' )

Both Boyle's and Charle's law of gases determine pressure of a "system" as temperature changes. It is the pressure exerted on the walls of a container by the molecular vibration caused by temperature. There is no mention in either equation of what the gas or mixture of gases actually consists of since at temperatures above liquidity, all gases (including water vapor) behave the same.

https://en.wikipedia.org/wiki/Boyle%27s_law

As to mining equipment tires, I have no idea why they put nitrogen in them verses any other gas, but I can tell you that temperature "stability" is not one of them.

In the following graphic, the volume is being changed and the temperature is fixed; thus pressure changes. In the case of tires, the volume is fixed and temperature changes causing pressure to change. The gas can be nitrogen or steam, it does not matter.

I agree, everyone is entitled to their own beliefs; just not their own "facts".

And to make it more confusing here is the formula.

P1V1/T1=P2V2/T2

P= pressure
V= volume
T= temperature
