Is the nitro fill worth it on tires for either mhs or cars? Pros? Cons?

Just do a search. It is not worth paying one dime for. The only difference between nitrogen and compressed air is compressed air can contain water vapor. The stories nitrogen does not leak back out is a myth. Nitrogen pressure varies just as much under load, temperature, and speed as good old compressed air.

Agree, but there are THREE choices:

Nitrogen, DRY, repeat DRY compressed air and WET air.

An air system with dryer will give you dry air which is very similar to Nitrogen in its properties.

Those coin op air compressors at convenience stores and those little portable air compressors don't remove the water. Water does NOT follow the ideal gas law (in terms of PSI change for a given temperature change).

I dont think it is worth it because when you need to adjust your pressure due the outdoor temps or loads your not going to have Nitrogen to use, I have a co2 tank for adjsting my pressures since I need 110 psi and the small compressors struggle to make that psi so I would be deluting the nitrogen each time . They say that nitrogen is not effected by tempature but I still think it is not worth it .

Planning on hitting the race track for a few laps?

Otherwise regular 'air' is already 78% nitrogen.

Nope. Not worth anything but won't harm if it's free. Comes from Consumer Reports.

Even if Nitrogen is perfectly dry, there is always some air in the tire and with it, moisture.


I fill my tires with a high tech mixture of 78 percent nitrogen, 1 percent argon, and 22 percent oxygen.

lets assume you have your tires filled with nitrogen, where do you suppose you will get air from of you are running a little low, the local nitrogen refill station? I will stick with nitrogen/oxygen mix, thats what comes out of my compressor

Eliminating the Oxygen inside the tire does nothing for the outside of the tire!

I don't see any Pros except for the seller.
