Re: [RC] [RC] Tire Pressure and Weight - Sisu West Ranch
"...doesn't
fluctuate with temperature changes like regular air,..."
A chemist (Boyle, if my old memory is still working
) proved ~150 years ago that in all gasses:
P=nRT/V
Where P= pressure, n = number of moles (amount), R
is a constant, T is absolute temperature (Celsius +273), and V is
volume.
In a tire the amount of gas is fixed and the volume
is fixed so the pressure does vary with temperature no matter what the gas
is.
The lack of water in dry Nitrogen will slow
corrosion and the lack of Oxygen (~25% of air) will also slow the deterioration
of the rubber. These benefits are most likely small, because most tires I
have seen crack from the UV and Ozone on the outside while the inside looks
fine. In the North both steel and Alloy rims look worse on the outside
than the inside.
As far as the rate of loss in pressure, both
Nitrogen and oxygen diffuse about the same rate, so again most likely not a real
big benefit.
I would put my time and money in better tires, and
checking the pressure at more frequeint intervals.
