Is it OK to run nitrogen in the tires? Anyone doing it?

Why Nitrogen?

Safer, smother ride

With under-inflated tires, there is less contact area between the tire and the road surface. This leads to less braking and steering control and a greater potential for blowouts. Properly inflated tires give drivers the control they need for a safer, smoother ride.

...

Longer tire life

Under-inflated tires wear prematurely due to uneven road contact. Maintaining proper inflation longer can help increase tire life. High-purity nitrogen-filled tires retain proper pressure longer, so they won't wear as quickly. Plus, replacing damp compressed air in tires with dry, inert, nitrogen can help to eliminate internal tire degradation and prevent rusting of the rim.

Convenience

With high-purity nitrogen tire inflation, you won't need to refill their tires as frequently

Oxidation

Air is about 1/5 Oxygen, and oxygen, especially at high pressures and temperatures, is a very reactive element.
When oxygen reacts with things, the process is called oxidation. When oxidation is extremely rapid, it's called "burningâ€￾.

That's one reason nitrogen is used in off-highway and aircraft tires. These tires runs on oxygen get so hot, they can actually catch on fire. Nitrogen doesn't support combustion, so nitrogen-filled tires don't add fuel to the flames. And nitrogen helps prevent slower forms of oxidation also.

....

Longer Rim Life

Rim rust caused by condensation from water vapor and other gases can get caught in valves and create slow leak in tires. Nitrogen is completely dry, so it eliminates the potential for condensation.

All points above are 100% valid for a car, not a bike tire, and aluminum rims.

Most sport bike tires are not on the rims long enough to benefit from the additional cost of the nitrogen. Unless you have a very cheep source I wouldn't bother.

I run a TPS system on my Busa so I keep very close tabs on my tire pressure anyway.
