I see where tire dealers are offering nitrogen for tires instead of air. Whats the advantage?

Markup for the tire dealer. Aircraft and race tires are filled with nitrogen so they don't start burning inside and fail as soon when grossly overheated.

Like someone said below it is suppose to be dryer and also more stable than regular air with less temperature fluctuations and leak out slower. It is also used to pressure hydraulic accumulators on machinery and has been used on aircraft and military aircraft for years.

Somebody said it keeps the aluminum rims from oxidizing. I wonder. . . Aluminum rims have been around all my life and I am 40. . . (We used to call them MAGS- but almost all of them were really aluminum.) Why did the problem show up now? is it so that these kids who put the 1" high "low profile" tires on those great big rims can get a little cushion?

I thought is was supposed to be better for the tires.... But I have never seen tires weathered on the inside?

A farmer friend had LP Gas tractors years ago and would use it to fill tires on wagons and other machinery.It sure was exciting when his shed burned .

I think there is more profit in pumping nitrogen into tires than there is air. If anyone would pay for it, they`d pump rose scented air into tires.

The main advantage is that bottled nitrogen is very dry, while compressed air contains a lot of moisture. Water vapor expands a lot more than ideal gases like oxygen and nitrogen.

I think the main benifit is that it inhibits corrosion in aluminum wheels.

Because guys have heard that NASCAR teams use nitrogen in their tires ;^)

High performance applications like racing and airplane tires benefit a little. It leaks out more slowly than regular air, doesn't support combustion, and doesn't oxidize the rubber or the rim. I can't image there's much benefit for tractors.

The pressure does not fluctuate with changing temperatures.

PV = nRT
That"s the ideal gas equation. Pressure P is obviously proportional to the temperature T.
Of course the pressure changes with temperature!
The only reasons are that they don"t want to be bothered with drying their cruddy compressed air and there are people out there prepared to pay a lot for very little! Anyhow, all my tyres have tubes in them.
For tractor tyres would be better to put in carbon dioxide as that would help some with ballast - much, much heavier than air and wouldn"t leak out even nearly as fast as air or nitrogen! Ok, Xenon would be even better!
