Nitrogen in tires?

Griffin said:
I don't buy it with the sensors.

They've been installed in cars for about a decade now, and I would guess most of them are operating in at least partially contaminated nitrogen, if not 100% gas station/home garage produced saturated compressed air. I know my tires pretty much run that way.

I've never personally had a failure, and I've not heard of any mass failures of them either.

Haven't had to replace one because the battery died?. Many do not have replaceable batts. Since they are potted in plastic I can't see oxygen or moisture making a difference.
 
I used to work for an industrial gas company. Nitrogen is an extremely dry gas,so it keeps moisture in the tire to a minimum keeping steel belts from rusting on the inside .Nitrogen molecules are bigger than oxygen molecules so you lose less tire pressure over time also.The machines they use are full of liquid Nitrogen, its vaporized into a gas,its 99% pure. I would use it if i could.

On aircraft wheel assemblies, think thousands to tens of thousands of dollars, it prevents or helps to prevent/reduce corrosion also. As others have said it also stabilizes pressures with the fluctuating temps that aircraft tires rapidly go through.

As for a bike or car....it could help reduce wheel corrosion for the everyday machine. No performance gains though.
 
If bull crap were 99% Nitrogen, it wouldn't be so difficult to get it into tires. But it would help with the Global Warming thing.
 
Since air is 1% water vapor I thought more was better, so I fill my tires with distilled water. I have to design a warming system when it drops below freezing up here in NE, since I ride in the winter too.

If you ride fast enough Coriolis force will keep the tires from freezing.

So if it is 0 degrees F out I would have to ride 18 hours of the day at 84mph with no more than 20 minute rest intervals to offset the rate of water freezing? With a windchill of -49F under those circumstances how would I keep my blood from freezing?

Installing nitrogen in your tires actually makes a huge difference in the electrical stability of the bike.

Doing this removed water vapor in the tires, the bike maintains 100% insulation from Earth ground and the electrons in the bike's system will not find escape paths.

In studies, this extends the life of the battery, bulbs, reduces corrosion and heat generated through the grounds.

Ongoing usage results in less parasitic loss through the charging system, which then pulls less power from the motor and this increases power output of the motor getting directly to the wheels.

This is compounded by the extra power found in the ignition system due to a more stable power and ground.

Wear a light jacket?
 
This is amazing.

I know how they all the air and therefore all the water vapor out of aircraft tires before filling with nitrogen, but how you get all the air and therefore all the water vapor out of your bike tires?

Fill them with nitrogen, then hook a vacuum pump up to the valve stem and pull to 500 microns. Then refill with nitrogen. (>.>)

I'm going to call BS on that one.

The safety bead on a tubeless tire will collapse at anything less than 600 microns, so you will never make it to 500.

Now, if you have a TUBE in your tire, you won't have any problem pulling 500 microns. :encouragement:
