You're better off useing hydrogen or helium, it makes the bike much lighter and acceleration is much improved.

main purpose of nitro in tires is no loss of pressure from hot and cold temp variations. For your location, I can't see how paying to have it put in would help you any. Up here in snowland, we have temps ranging from less than 0 to 95+ .  I would maybe consider it here but probably not.

Do they vacuum the original contaminated nitrogen out of the tire, or just dilute that nasty air with pure nitrogen?

They only remove the 22% that wasn't already nitrogen.  ;)

In theory dry nitrogen is an inert gas and won't attack the rubber or allow rims to corrode.  
But that slight amount of protection isn't really worth paying extra, imho, unless you're planning to store your vehicle for an extended (years) period of time.
Otoh, if they're charging by the cubic foot it should be cheap enough to fill motorcycle tires!

No jokeing here, there's a shop here that allows you to pay them a $10.00 fee and they give you an id card that has all your vehicle info including your tire info so they won't get screwed allows you to just come by and fill your tires up with nitrogen as needed. Of course if you buy new tires then you have to pay the $10 bucks again but all in all its not a bad deal if you want to use nitrogen.

Nitrogen has several advantages which is why commercial carriers are using it. The first is the molecule is larger so it is gas does not migrate through rubber. If you use natural rubber inner tubes this is an advantage. It does not contain oxygen so it does not oxidize the rubber inside the wheel, which is important. if you have tubeless tires you do not introduce water into the air chamber and rust the rims. NASCAR only allows nitrogen in the tires.

So if I fill my tires with air, let the pressure decrease 20% most of what is lost will be non-nitrogen nasties like oxygen.

I then refill with air, now my tires are 96% nitrogen, 4% nasties, I let 4% leak refill, I am now at 99%...


No money has changed hands, I get the benefit of cooler tires!

Now that's real science!  :D


Sure, I guess, maybe...

what if the leak is 78.000% nitrogen, 22.000% nasties?

Years ago I called Metzler (tires) and asked them about using Nitrogen, first question they asked was I headed to the salt flats? They all use it there. I used it in road racing slicks, drag slicks, and street tires, as well as my air shifters and dirt bike shock recharges. A bottle lasts a long time and wasn't that much to refill.

I should think the original air in the tires is the best way to go...

Nitrogen is fancy, but '70s air is cleaner.

The Disney Land monorail has nitrogen filled tires to reduce fire danger.

We always serviced aircraft tires with nitrogren in the Navy. The whole pneumatic system was serviced with nitrogen.

Do I need to swap out the Summer nitrogen that's in my tires with Winter nitrogen, or do you think I'll be okay just leaving it in there?

Nitrogen atoms have a life expectancy approximately equal to the rate of proton decay. so it has a half life approaching 10^32 years.  So 1,000,000,000,000,000,000,000,000,000,000,000 years from now,  1/2 of your nitrogen will be gone.

This neglects the fact that as the protons decay, your nitrogen will become become carbon, boron...hydrogen.

So, if I got this right I would only have to refill the tires around the time between now and the second coming. ;D ;D ;D
