You apparently don't know squat about the Laws of Gases. Now, Im again telling you that the ONLY reason is that the pressure to temperature ratio is more linear. Do you refute that? If so, do tell why. Now, I suspect that you don't UNDERSTAND my answer, and that is the reason that you don't think it's correct. So, allow me to explain. The nitrogen doesn't expand as much as air, for a given temperature change. Therefore, the nitrogen doesn't increase tire pressure as much as air, when the temperature starts increasing. Thus, a tire is less likely to expand, because of temperature increase, to the point of rupture. BUT, the nitrogen does NOTHING to keep the temperature of the tire from increasing, or decreasing for that matter. |

Rick wrote: You really ought to stop kissing fish, it has diminished your powers of reason. Basskisser whined: Well, then, please explain to the world how in the HELL nitrogen will make a tire run cooler. It doesn't. The tire heats the gas by conduction and radiation as it flexes. The gas doesn't heat the tire. Only reducing tire flexure will make the tire run cooler. It doesn't matter one single molecule what the gas filler is. Now, Im again telling you that the ONLY reason is that the pressure to temperature ratio is more linear. Do you refute that? Yes, along with many generations of scientifically literate people, I do refute that bonehead statement. Nitrogen follows the gas laws just as every other gas. Your interpretation of natural phenomena and physics will not change the gas laws for one gas in one application. The nitrogen doesn't expand as much as air, for a given temperature change. Therefore, the nitrogen doesn't increase tire pressure as much as air, when the temperature starts increasing. Please refer to the gas laws. You cannot rewrite them as much as you would like to believe you have. BUT, the nitrogen does NOTHING to keep the temperature of the tire from increasing, or decreasing for that matter. Well done, you are beginning to get it. However: You started this by writing: nitrogen helps tires run cooler Only because when nitrogen is used instead of air, the pressure to temperature ratio is more linear. Try and keep your story consistent. That statement reads that nitrogen keeps tires cool because it doesn't expand like air. Both statements are false. You may believe the gas laws are suspended for automotive applications but do try at least to keep track of your misapprehensions. I think most of this nonsense about nitrogen in tires not expanding as much as air comes from the fact that few people really understand the properties of gases. There is a little phrase in the gas laws that refers to "phase change" ... that is where the followers of the myth may be running aground - (boating content). Liquid nitrogen will vaporize to produce a volume of gas that occupies about 700 times that of the liquid. Liquid oxygen will vaporize to produce a gas that occupies around 860 times the volume. Vaporization is the phase change. Once the liquid has evaporated the resultant gas, nitrogen, oxygen, or water vapor, will follow the gas laws and when the correct law is applied (there are several) the properties of those gases are very predictable and if you understood them you would see that the properties of those gases are identical in their behavior under the conditions which race car teams and trailer boaters operate.

Rick you are a ****i## college educated idiot all in Christ world that was
asked was a method to keep the tires cooler nitrogen will period. You get on here and act like an ass! If I could get to you there are some physics lessons I like to show you.

"basskisser" wrote in message om... . You apparently don't know squat about the Laws of Gases. Can you please state which law you are referring to? I am familiar with Boyles Law, and Charles Law, the "ideal gas" law. I am not aware of any gas law that supports your claims. Now, Im again telling you that the ONLY reason is that the pressure to temperature ratio is more linear. More linear? The basic ideal gas law is PV=nRT. P = pressure V = volume n = the number of moles (a measure of the number of atoms) R is a constant (8.3144 exp-7) T = temperature in absolute units ("room temperature" is ~300 K) How do you get more linear than that? Do you refute that? Yes If so, do tell why. It is generally accepted that all gases obey the ideal gas law if you stay away from their condensation temperature. Air is mostly nitrogen, then oxygen, carbon dioxide, and traces of many other gases including water. Unless you have artificially introduced liquid water into the tire, or inflated the tire with air super saturated with moisture, the typical operating temperature of the tire will sufficienty above the dew point of the air inside such that the air (complete with water vapor) will obey the ideal gas law. The nitrogen doesn't expand as much as air, for a given temperature change. Which gas are you saying doesn't obey the gas laws: air or nitrogen? What temperature and pressure are you making this claim for? Rod |

Every time he types something he confirms he doesn't understand the world around him. I can't wait to see how he tries to weasel out of this one without admitting he's wrong. Stay tuned. Steve |

It is generally accepted that all gases obey the ideal gas law if you stay away from their condensation temperature. Not true. Unless you introduce nitrogen to the tire under ideal conditions, which would entail a vacuum process first. Do you really think that people are going to do that, when all they need is a larger tire? Air is mostly nitrogen, then oxygen, carbon dioxide, and traces of many other gases including water. Bingo, you're starting to get it. Water. Unless you have artificially introduced liquid water into the tire, or inflated the tire with air super saturated with moisture, the typical operating temperature of the tire will sufficienty above the dew point of the air inside such that the air (complete with water vapor) will obey the ideal gas law. Again, unless introduced under ideal conditions, there WILL be water vapor. The nitrogen doesn't expand as much as air, for a given temperature change. Which gas are you saying doesn't obey the gas laws: air or nitrogen? Niether. What temperature and pressure are you making this claim for? Operating range of the tire. |
