N2-only is a good way for the garages to generate revenue from drivers jumping on the 'next best fad'.

Under race conditions, pure-N2 fill can allow you to better control the pressure changes a tire undergoes as temperatures in the tire increase. It also allows for better tire-to-tire consistency. Unless you drive in conditions where .25 PSI variation is important (which can be in a race - good for the fraction of MPH you can carry into a corner), it's a waste of $$$. Also realize that most home tire pressure gauges will have more variation than that between readings.

Keep the pressures consistent, check every couple of weeks and don't worry about it - for 'home cooking', plain air is good enough...

From the General Discussion forum......there are a number of threads there on the subject.

This is all crapola, bs, fud, and is just a way to make money. It's just a hussle brought to you by people that figure you are too dumb to know anything.

You already have nitrogen in your tires. Lots of it. Everybody does.

Dry air contains roughly (by volume) 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1%.

So you already have 80% nitrogen in your tires already. What on earth would having another 20% add or not add to your fuel economy, the envrionment, global warming.....answer....not much. It's nothing but a money grab.

Notice the guy in the last video glossed over the fact that the TPMS sensors usually last 5 or 10 years. He goes on to say "some batteries are replaceable, some must have the sensors replaced." Well, at about $100.00 a pop, how would you like to replace your TPMS sensors every "5 or 10 years."

Let's see. The sensor is in the tire, rotates at freeway speeds, has heat and cold fluctuations to deal with. It has to deal with bumps, potholes, and how about flat tires that smash the damn thing. It has an infrared sensor in it, that transmits the signal to the ECU.

What could possibly go wrong with that system?

hahahaha good point- 80% nitrogen for free is works for me!

I really do hate TPMS, at least Toyota lets you set the pressure that it triggers at, and doesn't care about the sensor's position. GM is the most fail at it, requiring the position to be relearned every time you rotate them.

I wouldn't care so much, but it's only a matter of time before it's required to pass inspection, I can't wait for that, replacing all the sensors every 5ish years.
