Replying to: m6user (Jul 22, 2009 7:42 pm) I hope people don't really believe nitrogen is able to do all these magical things. Since the atmosphere we're breathing is 80% nitrogen, the nitrogen allegedly put in is responsible for great improvements based only on a 20% differential. consider that the machines that separate the nitrogen are not perfect, the air pumped into your tire may only be 90% nitrogen--read the disclaimers on the company's sites selling the nitrogen separators as "money-making machines" to tire stores. Also the use of nitrogen rich air was primarily a benefit to truck tires where the carcas is used for 100s of thousands of miles with recapping. I don't know anyone running their auto tires that long. If your tires go a long time without needing air: it's because the seal at the rim is good, the inner liner of the tire is a high quality sealer, and because the enviromental temperature went up from the original fill till the time you're measuring pressure now. (Pressure increases approximately 1 pound/10 deg Fahrenheit increase in temp.) As for keeping tires cooler, does anyone thing the heat transfer difference between 80% nitrogen/oxygen/CO2 and 95% nitrogen is noticeably different? Plus where does the heat get transferred to? Most heat will go out of the tire through the rubber to the atmosphere--not through the air within the tire to the rim. Most flexing occurs in the thick rubber layer with steel/polyester/nylon layers called the tread. The thinner sidewalls are designed to flex and produce less heat doing so. If the tire store actually used a 100% nitrogen tank souce like a hospital uses, then the claims might be considered; but they use a separator in the store which deteriorates in efficiency as used. The claims in some of the websites for sellers of nitrogen separators is faulty. Sometimes they trip on themselves claiming one thing in one paragraph as a benefit and the opposite somewhere else as a benefit. I found that when I spent some time last fall browsing sites. http://www.theautochannel.com/news/2009/06/23/466920.html |

Replying to: acdii (Jul 23, 2009 6:59 am) acdii, the Advantage T/A is a brand new design and everywhere I've checked they say "no reviews yet". By the way, the tire is for my Toyota Avalon and I am a moderate driver who prefer driving comfort and quiet over spirited driving. |

Replying to: imidazol97 (Jul 23, 2009 8:06 am) I have a 07 Mazda6 as well with plain air and have added air to those tires a couple of times a year since new. Usually about 4-5 low when I add. Those are Michelins. I added air to the two vehicles "in question" when they were running the OEM tires quite often as well. So you can see the pleasant surprise I had with the nitrogen. If in fact as you say the nitrogen doesn't add anything to the equation, they should pay the Costco tire installers more for doing such a great job.
