Stopped by the dealer today to see grab a few things for the bike. While I was their I asked if the would put some air in the back tire, and the service manager suggested putting Nitrogen. Said the biggest benefit was less variance in the air pressure inside the tire. Made sense to me so I had them do the conversion took about 5 minutes, and cost was 39 bucks. Seemed like a good thing. Just curious to hear what others think about this?

 

If air is good enough for your head, it's good enough for your tires...

 

that sun must really be hot in fl. lol

 

I inflate my tyres with compressed unicorn farts. Cost $3500 but the pressure never changes no matter what the temperature is.

Seriously scientifically speaking the universal gas law is

PV=NRT

pressure x volume = number of moles of gas x R (gas constant) x Temperature

R for air is 53.34, Nitrogen is 54.99, ie there is about 3% difference between N2 and Air. This is because air is about 79% nitrogen.

The difference in expansion rate as temperature changes is 3% - negligable.

Go ahead and use it if you like, its a liberty bell for your tyres.

 

I've heard that Nitrogen is better for the tires because you don't lose air pressure as fast, which in turn, helps the tire wear more evenly/correctly. I thought about doing it but when I researched it I couldn't find anyone who had done it that could say, "yes, money well spent"...I've stuck to putting in regular air.

Can you tell a difference?

 

Other than being $39 poorer? Inquiring minds want to know.....

 

The only way nitrogen would loose pressure slower was if the molecules were larger, and it took longer to make their way thru the rubber matrix.

Consider. air is 79% nitrogen, and oxygen is most of the remainder. The oxygen molecule is bigger than the nitrogen molecule, so shouldnt air stay inflated longer??

 

What is the profit margin for nitrogen vs. air ? $39.00/$0.00. Priceless.
