nitrogen in tires

[7uptruckracer]

It DOESN'T matter what you use. I consult with many asphalt AND dirt teams. What does matter is if you know where your RACING your tires. If you know you gain 4psi from Nitrogen as compared to 8psi vs Compressed air you can compensate to make sure once your in racing conditions your stagger and tire is performing how you want it. Why do you think the NASCAR boys can kill a Qualifying run with to low or pressures and why they start off race runs with low pressure or why if they have a late caution and pit the don't start off with pressure that would be for a longer full tire run. TEST take Cold PSI and Hot PSI sizes compare everything. Bleeders help you just have to be careful if you make a hot adjustment. Stop cutting people down on here a lot of use can post pedigrees or resumes but that's not the point some of us here just want to share information and help someone who wants help run better.

Nitrogen on a dirt track has no use, not even on a slick track. Tried it and it didn't gain us much. With compressed air straight from trailer compressor we only had a .5 psi gain on a very slick and dry track on both rears, and nitrogen was about half that, so .25 psi. I do not think that will make or break you. That isn't even enough to grow a tire.

Just wasted money on snake oil. PSI gains come mostly from poor throttle control, getting too sideways on a slick track, and spinning the tires down the straights.

72Dubya puts absolutely no heat in his tires at all. That's what he just explained.

I answered the original question I'm not sure why it pulled the quote I didn't think I clicked it. A cold tire is either the wrong compound, grooving, siping, or not checked immediately. Every compound has a different heat range you can check the manfacturer but to say someone is losing races because they are on compressed air is asinine. When at race temp and pressure they tire doesn't know what gas is in it. the error factor is the human working on it not the gas thats in it. If you don't account for buildup thats your own fault.

Go tell a cup team to go run compressed air 👍

When I raced asphalt I saw a significant difference between air and nitrogen. Like others have stated on dirt it doesnt seem to make a whole lot of difference. I think what kind of lubricant you use to mount your tires makes a bigger difference. The end goal is to have the least amount of moisture inside your mounted tire regardless of what gas you are using.

Cup is its own animal for reasons that have nothing to do with a dirt late model/ modified and quite frankly a cop out statement someone uses when their argument is shattered. They run a tire constructed totally different, dirt doesn't see the heat and buildup a Saturday night short track asphalt racer sees. Compressed air will not kill someones night, if you have the funds use nitrogen, if not their are many ways to get equal results on asphalt or dirt for your weekly racer.

Nitrogen is used for cars driven daily on the street to keep the pressure from fluctuating as well. The point is it is used to keep something on the car more "CONSISTENT". If you want things changing on your car run compressed air. If you want one thing to take out of he equation there are different gasses out to maintain pressures a lot better than compressed air. Lets see how trying to keep something more "CONSISTENT" is a "cop out". 👍

Its advertised for use by tire shops as a gimmick to prey on the uneducated and milk them for more money... Everyone with a lick of common sense knows this.

You couldn't be more wrong. You're uneduatced my friend. You stay at your dirt level with your hobby stock and 4 banger knowledge and leave he real engineers to knowing exactly why things are done certain ways. Also, schooling you right now they use nitrogen for the tire sensors so they do not fluctuate drastically from exteeme temperature changes. Now go get that bottle filled and make sure you thank me when you don't start sucking so bad after 5 laps in the dry. We will all be watching for that Nitrogen bottle.

We run nitrogen in our tires. It does help with keeping the pressures more consistent over compressed air. Now do I think it is the only reason we win consistently? Of coarse not. Not getting in the middle of a good argument but my approach to racing is this. If something helps even the smallest of gains why would you not use it? Everyone has all the big things it is the little things and the attention to the smallest of details that separate the good from the best.

Ok. In street tires it has nothing to do with tpms. Hell Chrysler doesn't even use tpms sensors on most cars. It's abt holding consistent pressure to reduce tire wear. And in NASCAR they use it because of the moisture content. Most compressed air is 17 % moisture content where nitrogen is around 12 and that could mean a 1-2 psi change in pressure between two.and 1-2 psi in NASCAR makes a big diff when running on asphalt which makes more heat anyway. In dirt it's abt a 50/50 shot either way. The track doesn't hold as much heat as asphalt and u aren't running 200mph for high lap counts so the tires don't make as much heat. Unless you ARE spinning hell outta your tires which then it really isn't a problem, it's the fool on the throttle causing the pressure changes

You my friend nailed it on the head. Words from someone wise and not this idiot Jeff Joldersma. This is why he won't EVER go anywhere. But we will be watching for the Nitrogen bottle haha. Everyone watch him and his pit for it.

It's actually the brakes causing more heat but nice try  Yes it does have to do with the tire pressure monitoring sensors. They also use it as a sale gimmick to all cars but the sensors would go off more saying warning and activate the stability control on cars once they drop usually 10psi low or te sensors crack.

Yes that too is another factor. So drive er in hot and slow er up fast and watch those tire pressures

You have no clue. Tpms isn't even linked to stability control, except for a few Chrysler vehicles that use abs wheel speed sensors to determine low tire pressure. All tpms does is activate a light/ warning when pressure drops 3-5 % mandated by gov. On all model yrs in 2008 . If u think temp change affects those sensors enough to where u need nitrogen to keep them from cracking because of a few % difference in moisture factor I urge you to talk to someone in extreme cold weather climates wher in winter it gets to -25 or better. Your reasoning would make it that they have to change sensors every day because of temp changes. And going from 32 degrees at morning startup to 150 or so because of breaking heat would that not crack them nitrogen or not? Your explanation doesn't hold water at all. And this is coming to you from an ASE cert. master tech A1-A8. L1. X1 P1 for 11 yrs now.

And how would you know the tires have been filled with nitrogen??? Any guesses?
