Is using Nitrogen a bunch of hot air

that's exactly why

Nitrogen is used because of the new TPM systems used in new cars. These units are made of metal. Regular air contains a slight amount of water vapor, and more is created with the heating of the tire. This water eventually corrodes the sensor units and contributes to their failing, ala the reason so many cars all of a sudden develop TPMS problems. Nitrogen doesnt contain any water vapor and therefore cannot corrode the sensors over time. It is used as a convenient cover up for manufacturers botched TPMS sensor quality. New units are being made of plastic, so nitrogen may see its way into extinction. You won't find this info anywhere or hear it from any dealer, only technician magazines, etc. Just an FYI, so spread the word, more people need to know of this scam and demand better manufacturer quality, not costly cover ups.

Nitrogen is not required. This is probably due to the valve stem sensor battery life failing before any corrosion issues. They claim 8 to 10 yrs but I've seen 3 to 5 yrs.
I work for Audi and it is not required to have Nitrogen and all dealerships do not offer it! End of conspiracy!

Just an FYI! The new TPMS systems are not going to require sensors in the valve stems anymore. Indirect TPMS is going to be the future for all vehicles.
This system uses the wheel speed sensors to monitor any change in radius/rotation speed characteristics. No sensors, transmitters, or receivers needed so swapping out wheels and tires doesn't require all the expense.

Audi is the first vehicle manufacturer that is standardizing on this indirect TPMS system right now. Like FSI, CVT and DSG, other manufacturers will follow with their versions.

As far as the Nitrogen goes, Those who have used it should be who chimes in. I thought it was bull untill I started using it. Simple as that. I have customers who deny and tell us it's bogus and throw all their knowledge on why, and that's fine. First hand experience doesn't lie. Definately coming from a sceptic!

It has its good sides and bad sides... I've used it and you really can't tell the difference. Its suppose to make your tires wear evenly. IMO its not worth it. I believe I paid $50 for all for tires and unlimited refills. Bad thing is that if you have a leak, you can't fill it with air at your local gas station. I'll wait until it's available everywhere including gas stations..

Balance, alignment, the proper inflation of tires, and how you drive, are the determining factor on tire wear.

All that kind of information has so little bearing in real world settings and is used to market nitrogen and to cover up its true reason for being used.

Snakes709 · 04-25-2010, 11:22 AM

i leave my front tires alone and have it filled with nitrogen, my rear tires i fill with air due to me lowering the psi every week when i race and refilling soon as i leave the track.

Whats happening is a reversion back to the way old low tire monitoring worked, using wheel speed sensors instead of in-wheel sensors.

As far as the conspiracy is concerned, manu's didnt start using nitrogen until they found out regular air was causing sensors to fail. Dealers could either choose to use nitrogen, and profit immensely off of it by selling hyped-up performance BS, or not and make immense profits off of replacing sensors and reprogramming them. Rip off central either way you see it. Not all manu's do this, but the ones that do, shame shame.

I like the old system of using a wheel speed sensor better, like the old buick/cadillac types.

We really don't make a huge profit, generally give it away anyway.

Read this article: (esp. last paragraphs) Audi is currently the first user.

Buick?? LOL

yes, buick, and cadillac, among others. this new audi thing imo is just another overblown euro designed gadget thats too expensive and fancy for its own good. quick question too, are you gonna fight me on everything I say like it holds no merit at all?

Just provide a source seperate from you is all. There is a lot of garbage on forums!!

Usually from folks who don't work in the industry.

I could go scourer the internet for a source, but youll just have to take my word, I am a mechanic after all and have no reason to deceive you. Ive fixed many a wheel speed sensor because of the low tire light. The system isnt nearly as technical as your audi system, but it has been around for a while.

I live in Canada, when I had my 07 Nismo frontier in the winter, temps would drop to -30C at times. With air in the tires, they would leak on every cold day to the point of becoming totally flat. After a -35C tire change at night, I said no more and filled them with nitrogen, after that they stayed filled through the rest of winter.

6spd · 04-25-2010, 05:12 PM

you can top off with regular air if you want.

nitrogen hasnt really helped my tires wear evenly lol
