True. I can correct for the excess CO2 in the air mass by offsetting it with a few carbon footprint reduction expenditures elsewhere. I bought a dog that craps everywhere causing weeds to grow that absorb the CO2.
If they are OEM sensors, they do not have a significant error due to temp increase, they are quite accurate.

All the cup cars use it.

You gave it away! Ya had wiley coyote going there for a momnet.

Bingo! Also used in the air guns.
I left MA with 32 psi in all 4 tires. Now they are showing 37 -38 psi he in FL
Well, the ones on the Charger aren't. I've set the pressure a few times with the same guage and can't get all 4 to read the same after moving the car. I've kept it out of the sun, driven it in a straight line, let it sit all day and tried it at night, Backed out of the garage and right back in and there is always one that is off a pound or two. It varies as to which one it will be.

The "average" person doesn't know what they want. Yes, they will eventually go to a tire vendor, but they tend to be a bit clueless when it comes to making an intelligent choice.
True enough, and when the price is the same between store X and store Y, they'll look for something to finalize the decision. Nixon lost to Kennedy because he 'looked' unshaven in a televised debate.
Neither of which nitrogen will prevent or avoid. Nitrogen still diffuses thru the rubber, it just does it at a slower rate than compressed air.
I know of no passenger car/light truck tire manufacturer that mandates using nitrogen to fill, in fact, a few have debunked the supposed benefits.
I assume tire PSI sensors are nothing more than miniature force transducers. They use strain gages to measure deflection from force or pressure. If temperature changes then the transducers flexure expands or contracts. The gages don't know the difference and show an error. I'd be interested in seeing just how well they are temperature compensated. If the error is repeatable between different sensors then the error curve could be programmed into the computer.
As I understand it, the nitrogen will not absorb moisture as air does. So if you aren't into autox, regular air should work for everybody.
I know air guns use it, it all I use in my paintball marker. I know of the reason/advantages in the paint marker, I was thinking that is truck tires in AZ it might have some benifit.
I fill my tires with 78% Nitrogen, 20.95% Oxygen, 0.93% Argon and
0.04% CO2.Seems to work well.

You guys are all so funny!! I am sure that Denny and Roy fill theirs with methane after eating all those nasty burgers!
WTF!! It is the friggin' Rabbit that is trying to pay off all those football bet's he lost to me last year with White Castle burgers.
I'm saying foul, I want a steak!!
Personally, I suggest you try more Argon. At 0.93%, it's feeling a bit left out. And ... because it has 18 electrons (2 + 8 + 8), it will make your ride more stable.

How about some Hosenfeffer (sp) !!
The "funny" part of this is that "air" is about 78% nitrogen. Nitrogen is a bit more stable than air with tempature increase but the biggest plus of nitrogen is that it cannot hold humidity. ALso on the leak theory, only the oxygen molecules would leak out if you went with that and that would still leave 80% of the "air" volume. When I was around F4 many years ago they used to use nitrogen in their main tires foe to reasons, one was it was a little more stable and the other is that it did not support combustion because when they got hot brake on F4 they would tow they over pucture strips to "blow" the tire before heat did and the was no burst of oxygen when it burst to fan a fire if one starts. In a car it is like more than a novelty

This topic comes up regularly in aviation groups. You can read this discussion that begins with "Michelin recomends inflating tires with nitrogen."
Some comments from Drew Dalgleish stand out:
"At work I run a large front end loader. About a year ago the company switched from air filled to nitrogen filled at the recommendation of the tire supplier. Used to be at the end of an 8 hour shift the tires would be hot to touch or too hot to touch. Now they're just pleasantly warm."
"Tire pressure is checked daily and hasn't been changed. Heavy equipment tires are expensive ( $5000-20000 for the ones we use ) and there's now up to a 6 month waiting period for new ones. They take tire care seriously where I work."
