Any of you guys get your tires filled with nitrogen?

Kinda sounds like a gimmick is this actually helpful?

 

yeah, you can use nitogen.

It doesn't lose psi as fast as air. But air itself has nitrogen in it,just not fully. Most track race cars use nitogen to get and keep better PSI in their tires.

 

it is supposed to yield slightly better gas mileage due to the constant psi in the tires.

 

I did it on my tires. Kept the pressure in for a few months.

 

Most racers use it. More consistent.

 

also it's lighter than air, so your tire/wheel will be actually be lil lighter

 

we used it on our race cars... with 10 inch slicks on our asphalt pro late model... during a 10 lap hot lap session our tires could gain 10 psi on the right side tires... with nitrogen, there was maybe a 1 psi gain if any... its much more consistant and it does not expand when heated such as air...its good for racing because you can predict the tire stagger and pressure throughout the race much easier...

 

It is better mostly because it has no water in it. Water is what does most of the expanding in air when it is heated. You could use pure Oxygen but that would up the fire risk. The big advantage definitely that it is more predictable, since you know the contents for the tire about as accurately as is possible.

the Nitrogen molecule is actually smaller that both the Oxygen and Carbon Dioxide molecules that make up a good chunk of "air" and would actually leak more quickly because they will fit through a smaller hole.

It is a little bit lighter, but we are talking grams if that per tire.
