[SARCASM]Nitrogen will make a Camry perform like a GT-R because GT-R tires use nitrogen. [/SARCASM]

 

removed previous reply....

New reply: can't imagine there being that much moisture in the air to cause damage to the pressure sensors, but then again i live in California.

 

I've misread a post here and there myself so no big deal, but I think they're talking nitrogen in tires with tire pressure monitoring systems. Someone's trying to sell it based upon the fact compressed air often contains some moisture which may damage the sensors.

 

Correct. Though Goss wasn't selling it too hard. He just kind of mentioned it.

 

Compressed Nitrogen contains little if any water. I use those coin operated air compressors at gas stations and I could see on very hot humid or rainy days you would be adding a significant amount of water vapor when adding air to your tires. Then when the air temperature drops it's possible to get condensation forming on the TPMS. Not an issue for you folks living in the southwest though!

Now where do I find compressed nitrogen to top of my tires? A tire shop I guess?

Costco uses nitrogen when you buy tires there. I'd think they have a top off service.

 

I like nitrogen because it is consistent and doesn't fluxuate much under harsh temperatures. I really do feel like it's the better way to go compared to normal "air." I was already loyal to Costco but since they changed over to nitrogen filled tires, I really don't go anywhere else now.

If you ever played paintball, when you shoot from your marker (gun), air or CO2 filled would have erratic consistency depending on the temperature while nitrogen would be consistent throughout the day till your last shot.

 

The moisture factor in compressed air is not that great at "competent" shops due to the fact they try to "dry" the air after it leaves the compressor. Trust me, mechanics don't like running wet air thru their air tools.

Another benefit to nitrogen is the molecules are bigger, resulting in less air loss in the tire over time, and less pressure increase with heat.

good info:

http://www.scientificamerican.com/article.cfm?id=nitrogen-filled-tires-fuel-efficiency

"air is composed primarily of, you guessed it, nitrogen; some 78 percent of the regular air you put in your tires is nitrogen, with oxygen making up most of the remainder. So going to pure nitrogen only squeezes out a small amount of the oxygen molecules that nitrogen proponents argue are so detrimental”

 

Here's the info from the MotorWeek website http://www.motorweek.org/features/goss_garage/tpms_maintenance

 

it says on the motor week article that moisture comes from air compressor. i'm using my manual bicycle pump to add air to my tires. does that exempt me from moisture?

Air compressors do exactly what the name implies. They "pack" air into a confined space. In doing so, they also pack any moisture in that air into the same confined space. When the pressure is released, i.e. when you inflate your tires, that compacted moisture is released into your tire along with the air. Most commercial shops have built-in dryers that remove most of that moisture.

Now, for the guy with the bicycle pump. It appears to me that your "compressor" is no different than any other when it comes to collecting and releasing moisture.

 

There has been a discussion on Nitrogen on the Camry Hybrid forum and here is a search on Nitrogen from that forum and the various threads:

The question I have is I haven't really here of someone who had this problem and I wonder how long it takes to rust and fail?

I bet it's a long time.....!!

Most tire places check them and you will be replacing your tires (20K+ Bridgestone to 50K+ Michelin) over time.

 

Is the tire pressure sensor on the valve stem on a Camry? Thanks

 

Yes .... should look similar to this. It does not look like there's much to rust there.

I'll stick with my 12V air compressor which worked fine on my last car that I had for almost 9 years which had TPMS, and I'm sure my Camry will be just fine with regular 78% Nitrogen from this compressor.

Air compressors need to be maintained and drained. See this interesting site to learn more than you ever wanted to about water/moisture and air compressors.

I've been using normal air for......... I lost count. It's fine on my tpms.

You guys might be fine waiting 2hrs at Costco to get your tire fill with N. I'll do mine in 5mins and get on my way.

Simply put, normal air works fine. And N you don't gain much while a lot more hassle getting it.

just don't pump your air when it's raining like crazy.

 

money grab?

What I found interesting was when we were negotiating a 2012 XLE last weekend, the dealer automatically added $395 under dealer "options". When I questioned the sales guy on this, he said, "Oh, that's the nitrogen package, we put that on all of our vehicles". After pressing him a bit further, the "package" is filling the stock tires with nitrogen and warrantying them for 3 yrs.

Is it just me, or is that a rather transparent money grab? Since we need winter tires which won't be purchased from Toyota, effectively we're really only covered for 3 summers, not 3 years. Also, I believe you can get nitrogen top-ups free at various places. I mean, I can see some benefits to nitrogen, but $400 plus tax?? Really?

We thought it was rather ridiculous, especially seeing as they just added it on without discussing it. We were able to get it removed from the quote, however it was only when we said we'd buy the car, on the condition that pkg was removed... or we weren't interested.

:wtf:

Pretty ridiculous. Way worse than the $99-$199 window etching charges I see, IMO.

 

^ at least you are getting something semi useful to you. Last year I paid over $18k in tax to a gov that use that money to put speed cameras to punish me, and destroy some perfect condition side walk to replace it with the exact same thing... at least I see it's not any better or worse yet.

 

I thought i had it bad paying $5K to a county that decides i need to pay an alarm fee too since having an alarm causes more work for police :facepalm:

yeah but that charge is a rip. You aren't getting $400 of benefit. I'd deflate it and ask them to put air in and take the charge off
