Fill up at work! And send me some bottles!
Honestly, if it costs to much and is a big hassle just stick with air. There are good reasons for using Nitrogen in tires. Compressed air is cheap and readily available. I just need to get an inline air dryer for my big compressor now, it makes more water than air now a days.  |

I use nitrogen in drag slicks...it makes a huge difference in maintaining proper pressure run to run.
I also use nitrogen as a purging agent when soldering copper tubing to prevent oxidation and scale. |

I have a crazy question. If the tire is mounted on the rim what is already in the tire? Normal air right. So how do you purge that air/moisture out, because if you do not then what is the point of putting nitrogen in? Wouldn't you just be mixing the two? |

If a tire gets low on a ride, can I mix with pump air, or spend another 40 bucks for a couple pounds of nitrogen? |

You don't seem to understand that your tire won't go down. If it is going down, you got a nail and at that point it doesn't matter whats in your tire.

Without filling the tire in a vacuum, you are right there will be some oxygen and other impurities in the tire, but the amount is negligible. |

Froggy,
I hate to disagree, but, page 46 of my owners manual states "Solo Riding- Frt 32 p.s.i. Rear 36 p.s.i - Loaded to GVWR Frt 36 P.S.I Rear 38 p.s.i.." The difference between the dry weight of the bike (465.18 lbs.) and the maximum GVWR (850.98 lbs) is 385.80 lbs. Although the combined weight for my wife and I plus gas and luggage still leaves a little room to the GVWR it is still heavier than just me on the bike. So therefore I should add air.
I also read on the Dunlop site last night that all of their touring tires should be set at 40 p.s.i. for two up riding.(I am using Roadsmarts)
Are my calculations correct or have I been inhaling too much nitrogen? |

That is interesting, I even looked online, they say same as solo on the 06 Uly.

Perhaps you got less Nitrogen in your Canadian air. 
I will do some research, but I doubt 2psi is going to kill you.
(Personally I would be running 42psi) |

Wow, that is strange Froggy. I can't believe that adding an extra 100-150 pounds for a passenger wont "flatten" the tire out some. I worry about the inflation as overheating the tire is not good, although the riding is very tame when the wife is aboard. I'm afraid of overinflating too and wearing out the centre of the tread. |

I've been waiting on a bottle of Nitroegen for over a year (some friend) I may have to go rent a bottle now that you guy's have re-lit the fuego. |

There is a website called the straight dope. According to that website, the average user would not see a difference using nitrogen. Also per the website, Airplanes and NASA use nitrogen to reduce the risk of the tire overheating and catching fire.
The main issue is the moisture (humidity). Dry rot and leakage are reduced but still not significant.
If you can get nitrogen for free go for it. I'll stay with air and just check my pressure frequently. |

Looks like "straight dope" just debunked the nitrogen theory. |

I'm not trying to piss in anyone's cereal here but it's not a "theory" it's proven. And yes the "average" user isn't going to see any major differences. The key point to nitrogen is the reduction of water and the constant pressure it provides in a tire. For some serious applications it can be a life saver. To put it simple. If I had a readily source of it, I'd use it because I have used it before in vehicles and it's awesome not to have to worry so much about permeation.
It's not a hoax, it can be expensive, so use if ya got it, eff it if ya don't. |

Good read Firebolt32. I have been meaning to pickup a tire pressure system to put on my bike.

I learned 2 things by reading the (2 year old) article above:
1.) The reported mileage increase in your tires is based on the assumption that we were all running our tires low on air pressure before, and will only run them at proper pressures with Nitrogen. Another fantastic example of how you can use statistics and "studies" to support any opinion you want.
2.) A guy who sells Nitrogen inflation systems thinks we should all run Nitrogen in our tires. Shocking...
This has all the makings of another "which oil is best" debate!
The real news to me was reading about the supposed new tire monitoring requirements that I was not aware of (though my 2007 truck has one that has never gone off).
The number of laws/regulations and new requirements that car have to meet is ridiculous. |

Yep by law all 2006 and newer automobiles have a tire pressure system. My 2002 Monte Carlo has one, the only time it tripped was when I was using the spare. The way it works on my car was that it uses the ABS wheel sensors to pickup different wheel speeds. Too much variation in speed and can tell you are a few pounds of air down and will trigger the light. Some cars use a sensor mounted in the rim or valve temp that wirelessly reports to the car the pressure. Those can be a bitch if you rotate the tires and don't reset the system. |

I have never heard of that TPM. Are they hard to just disable and pull them out? If I read that correctly its like needing to have a check engine light reset by a dealer. More crap to pay for that I don't want. Just like onstar. |

Very hard to remove without messing up something else. On my Monte, it is tied into the traction control and ABS systems. I would have to defeat them in order to bypass it. But rather than go through all that effort, I just keep my tire pressures correct....
I just ordered the TPMS for my Ulything, I can't wait to get it installed |

I understand that part. But in reading the article if the tires do ever trip the monitor - you have to take them into a dealer or certified shop to get them reset. My dad had a GM truck that tripped the check engine light. My boss had the same issue with a toyota tacoma. He had to take it to dealer to get it turned off. I don't remember how much but in both cases it was a fking ripoff amount of money.
I can check my own tires and don't need the extra expense and complication of more monitors on any of my vehicles. Besides it seems like a TPM will lull you into a false sense of security just like an oil pressure gauge. That tpm won't tell you when you've cut a sidewall or picked up a nail until its too late. Theres more to inspecting tires then just throwing a gauge on it. |

I have not seen a vehicle that requires a dealer trip to reset. To do it on my car, its listed in the owners manual to do it with a button combo on the radio. Some cars just auto sense the added air and will reset itself. As for the GM truck, it will not trigger a check engine light, it will say "Check tire pressure" or something similar, then you whip out the owners manual to confirm how to reset it. I can't vouch for the Toyota, but I would imagine it would be similar.
Actually you are wrong about the false sense of security. It is constantly monitoring and will alert you. If you are out driving, you pick up a nail and start losing air quickly like a pound a minute, you will find out long before the wheel starts shaking.
You are right that there is more to inspecting a tire than using a gauge, but this isn't about inspecting tires, just like there is more about oil than keeping it above the add line on the stick. |

Correction to my above post. The GM and Toyota thing were about the check engine light. Once that was tripped the only way to turn it off was a trip to the dealer = $. It didn't have anything to do with a TPM.
Actually you are wrong about the false sense of security. It is constantly monitoring and will alert you. If you are out driving, you pick up a nail and start losing air quickly like a pound a minute, you will find out long before the wheel starts shaking. But I don't think thats either the intended purpose or the way it'll be used by 95% of folks. It'll be just like the check engine light to most people. If its not on theres nothing to worry about. IMO its law because most people are too lazy to check their pressure periodically not for preventing accidents. Once again other folks laziness will cost me money due to increased complexity of vehicles thats not required. I still think this will give a false sense of security to the lazy.
The whole point of that one article is that the TPMs are very sensitive and thus nitrogen was recommended. The article also mentioned that a trip to the dealer was required for reset. I'm not arguing that a TPMs not a useful tool. I just don't want to be mandated into having to deal with them. |

Unfortunately you are right, the TPM is forced on us because of lazy people. This is result of the whole Ford Explorer / Firestone issue going back about 10 years ago. Either way, I am embracing the technologies, I love farkels wither I really need them or not. |

Thats cool. I'm really not into farkels at all. In my experience when something starts to go wrong with one of my toys, it's usually farkel related. |

Mike have you never heard of Autozone? Any of the parts stores will read and reset your codes for free. Hell you probably had to go to them to read the codes and figure out the problem to begin with.
Dealer required bs is just lazy people not willing to think. |
