So I'm at the Nissan Stealership Thursday morning for some warranty work on the Titan and I ask to have the low tire indicator light reset amongst other things. I'm told that I'm out of warranty for that particular service..:shaking: Oh well no big deal but than came the hard sell on Nitrogen filled tires which doesn't have the temp fluctuations of air apparently? They wanted $40.00!? They would then reset my tire dash light indicator and warrant the nitrogen!........I declined but wot-the-heck!?
Any inside thoughts on nitrogen filled tires? Should I have taken them up on there offer....?
 
so let me get this straight....you truck tires have air in them now and they wanted to deflate them and then inflate them with nitrogen, and then wouldnt put just air in your tires to inflate them to proper PSI?

Yup, complete deflate and then inflate with nitrogen and warrant that!.....
 
the real advantage is nitro is dry so it wont corrode your tpms. compressed air has alot of moisture. the rest of the stuff is bs if you ask me. if you check your tire pressure regularly let it fluctuate, who cares? if it werent for the tpms i would say air is fine but those sensors will last longer with nitro. most places are about $8 a tire, so those prices are about right.
 
We charge $49.95 here to do it. The only reason I had mine done is that nitrogen isn't nearly as temperature sensitive as free air. The pressure remains constant. Plus we get our tires done for free.
 
It only works (better fuel mileage, etc.) if your tires don't leak down, otherwise you're throwing you $$$ away unless you have nitrogen around to constantly fill your tires back up to proper PSI
 
with the mpg what theyre saying is if your tires are low youll get bad mpg so if your tires stay constantly full better mpgs. i would say check your tire pressure regularly(when you fill up with gas) then who cares if you have to add a little air? 50 maybe 75 cents a month.
 
i dont know about the air pressure, i heard it's because nitrogen is lighter than air and threfore theres less rolling mass to turn and that nets you better mileage.

Well, as for teh cost... air is freely available, well, everywhere... but nitrogen isn't... given the total volume of 4 tires, $40 isn't rediculous.
Yes, "air" is 78% N but it's the other 12% that causes the "problems".

I dunno, if I'd just bought nice new tires, I might go ahead and do it just so I wouldn't have to check my tires as often... that's only like 8% of the cost of tires anyway.

Like how they make 7 bullet points by re-phrasing the same ideas 3 times.

Now, what I want to know is - why not use HELIUM to decrease the weight???:lol:
 
lol... i think i better quickly point out that i have plain old air in my tires.
 
Its a good thing you left the stealership before they tried to sell you on the blinker fluid service plan. Its on $10 more if you go with the nitrogen plan. :lol:

<><Fish
 
Because from what ive noticed, helium is very temp sensitive. I have a nitrogen tank here at the house I use for my junk

so if your tires are fully inflated whether it be air hydrogen or farts you will get the same mpg. i mean, how much does the volume of air in a tire actually weigh? you could get a better mpg gain if you hit the gym and lost 5 lbs.
 
Like they've said, nitrogen doesn't fluctuate as much with a temp change. Off roading that may not make much of a difference, but for long highway trips or racing applications it does. It also helps the whats on the inside of the tire, as there's no moisture. I keep a tank of it for my tires and such, 20 bucks a fill and that nets me a ton of fillups...
 
Total bullshit. It's been a gimmick for years and years. The "scientific" aspect of it is that a nitrogen molecule is larger than an oxygen molecule (barely). Therefor the tire leaks slower and a properly inflated tire gets better gas mileage. The main reason racers use it is the lack of moisture in the N. There is a more consistant pressure to temp change...nitrogen still expands with heat too, it's not magic... The correlation between F1 car tires and car/truck/trailer tires is ridiculous anyway, but the main selling point of a shop trying to make money. Your tires get nowhere near as hot as a stock car, and the half pound of air pressure difference isn't going to make a bit of difference. It is a way for shops to make some extra money, plain and simple. Especially during the winter when people magically get "flats".

If your tire is leaking, it is going to leak either way...and just as fast.
