Question Question about Nitrogen

Heard that filling your tires with NO2 helps a bit with mileage and other minor perks. If so where does one fill your tires at with this? Im up in North Florida so hmmm any help is good~

PS I know oxegen is 78% NO2 so yea..

Oxygen is 0% nitrogen. Air is 78% nitrogen. Air is 1% water. Nitrogen is 0% water. Because nitrogen contains no water it doesn't corrode wheels or tires. Its pressure doesn't vary as much with temperature. It doesn't improve fuel mileage if you check your pressure regularly. I get it free, but don't think I'd pay for it.

Nitrogen at 40 psi will get the exact same mileage as regular air at 40 psi. the advantage is in high-performance track vehicles in the consistency as they heat up on the track there's less pressure change.

If you have corrosion internally from moisture...wow. stop filling up the tires with the hose?

To fill tyres with nitrogen you first have to purge ALL the air out which means at least three changes of gas.
ie: Let all the air out. Refill with nitrogen and let that all out. Repeat and finally fill with nitrogen to the required pressure.

After you fill them with nitrogen you have to keep filling them with it so your options on pressure checks and fills are limited.

Finally it has been tested by a few motoring organisations , here in Australia as well as some in Europe , and has found to make no difference to fuel
consumption.

If you want to go ahead I would be interested in what ever you find from your trials.

Cheers , Pete.

Nice.

Really, if you want to fill your tires with some specific gas, why not helium? It conducts heat better than air, is a noble gas making it chemically inert, and is less dense so you'll at least be lugging around a few grams less mass.

they use it in air plane tires because of the tempeture change between being 1,000's of feet in the air where it's cold and having the tire hitting a runway and suddenly heating up.
nitrogen is also inert, and dry, so it will not brake down the rubber, nitrogen molicules are also reasonably large, so they are less likely to seep thru the poors in the rubber.
in my mind nitrogen filled tires would be best for vehicles like motorcycles and bicycles, they often have tubes, so purging is not an issue, and it will make the tire last longer while in storage.
