Every mid 90's Ford Exploder came with these tires from the factory, tireblast indeed.

The trip that is documented in my signature (third link) was my first ever over 30mpg.
I reallt thing the nitro played a role in that.
There must be another explanation. Does anyone really think more pure N2 is exempt from Boyle's law?

Boyle? Wasn't he that guy who played Frakensteen? I didn't vote for him, so why is he making laws?

LOL.

Quote:
Boyle's law (sometimes referred to as the Boyle-Mariotte law) is one of many gas laws and a special case of the ideal gas law. Boyle's law describes the inversely proportional relationship between the absolute pressure and volume of a gas, if the temperature is kept constant within a closed system.[1][2] The law was named after chemist and physicist Robert Boyle, who published the original law in 1662.[3] The law itself can be stated as follows:

For a fixed amount of an ideal gas kept at a fixed temperature, P [pressure] and V [volume] are inversely proportional (while one doubles, the other halves).
I guess in this case, the temperature varies with a more-or-less fixed volume, so the pressure is proportional to temperature.

P*V=n*R*T

P: Pressure
V: Volume
n: the ammount of molecules of gas
R: 8.3144621 (gas constant which is the same for all gasses)
T: Temperature

The above equation says that no matter the gas for a given change in temperature their will be the same change in pressure given a fixed volume.

He was making laws before you were born.

Tell you what I'll sell you a filter that will filter the nitrogen, for $200.

It will pay for itself in less than 10 fillings.







disclaimer: depending on atomspheric conditions the concentration will vary

I have been giving this some thought, and while I agree that it shouldn't really matter what gases are used (air vs N2) to inflate tires, I do think that not enough attention is paid to water.

That's right - water. If humid air is used to inflate tires, then it is possible for the evaporated water to condense out as the tire cools (especially if the tire is initially inflated during periods of warm weather, and then that same tire is used throughout winter). Such condensation will significantly affect tire pressures. That would explain why mcrews saw his tire pressures vary as significantly as they did before he used N2.

I say fill your tires up with pure carbon monoxide, it would virtually eliminate oxidation issues.
