Nitrogen in tires?

[Cipher]

Rapid Ray in the real world what real benefit does one derive from nitrogen?
It is a dealership scam. Tires have had atmospheric gas since the dawn of the pneumatic tire with no real ill effects.

Just like many have said nitrogen is used on aircraft for two reasons, no moisture and less pressure change due to thermal changes. Aircraft fly in all range of temperatures and as such the tires might see -30° to well over 100° in less than an hour. Those tires have to maintain a fairly constant pressure throughout the entire range. Nitrogen in race cars/bikes is for the same reasons more constant pressure. I say more because I know aircraft tires will still change presure due to temp as much as 10 psi for the little ones I work on. Race vehicles are pushing the tires to their limits and as such want to stay as constant as possible. As for a car or motorcycle for normal driving Nitrogen is a waste. Just my opinion.

I should imagine it is also a waste for most racing oriented driving.
Even an imaginary edge is an edge?

For racing applications, where every tiny bit matters, it may be justified.

For street riding/driving, it doesn't make a difference.

H? or He?

Hydrogen? or Helium? I've got a call in to Tom Brady ("I misinterpreted the rules").

No nitrogen, but I have used Metric air for some time now...

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.

Bull crap is 99% nitrogen, so I heard.

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.

I run my tires with only 78% nitrogen.

I run my tires with only 78% nitrogen.

I always go for that extra 0.4%.
