does anyone around the area have nitrogen filled tires? opinions?

Luke@tirerack

if you feel you need it .... I bet you probably also think the dihydrogen monoxide should be banned since it can kill you

as tires heat up and in between seasons and also reduce moisture buildup inside the tire but frankly, I cannot tell the difference. The pressures on my nitrogen-filled tires seem to vary just the same as normal inflation and at the rate we all all burn through tires, it doesn't really matter whether they're nitro filled or not

but figured it'd be worth a shot to ask.

It is thermodynamically impossible for the pressure to remain the same if temperature changes.

All gases follow the ideal gas law PV=nRT(with minor corrections).

Where P=pressure, V=volume, n=# of atoms, R is a constant to compensate for units, and T= temperature (on an absolute scale).

If V, R, and n stay the same, then a change in T forces a change in P. It has to, no sales tactics here.

Remember, the temperature scale is absolute. It must be either Kelvin (metric) or Rankine (English). So a 10 deg F temperature change is a large percentage of 70F (14%), 70F on the absolute scale is 529.67 Rankine. The 10 deg change is now 1.9%.

But there are other benefits to running nitrogen, so keep using it if you want to.
1. It is usually moisture-free--so it won't rust the inside of steel wheels (ours are alloy and don't rust).
2. It is oxygen-free--so it will not oxidize the inner surface of the tire.
3. It is technically lighter than compressed air--by about 3%.

I will stick with compressed air, it is free, available almost anywhere, and not fatale to humans and animals.

Sales people using false info is a pet peeve of mine, sorry for the rant.....

if you are going to run a 500 mile race in 4 hours now that's another thing

Public efforts 'against' DHMO

* In 1990, Eric Lechner and Lars Norpchen circulated a DHMO contamination warning on the UC Santa Cruz Campus.
* In 1994, Craig Jackson created a web page for the Coalition to Ban DHMO. The page spread widely on the net and off, including publication as an "ad" in a 1995 issue of Analog Magazine.
* In 1997, Nathan Zohner--a 14-year-old, junior high student at Idaho Falls, Idaho -- gathered 43 votes to ban the chemical, out of 50 people surveyed among his classmates. Zohner received the first prize at Greater Idaho Falls Science Fair for analysis of the results of his survey.
* In 1998, drawing inspiration from Jackon's web page and Zohner's research, Tom Way created the Dihydrogen Monoxide Research Division (DHMO.org) web site as a fun and educational resource for teaching about critical thinking and information literacy.
* Kate Dalgleish and Mikael Sydor--high school students from Calgary, Alberta, Canada--circulated a petition in April 2004 to ban the chemical as part of the Western Canada High School film festival. Several high school chemistry teachers and university science students signed the petition, which asked the municipal government to ban the 'dangerous chemical' under a fictitious Hazardous Chemical Act. Their film won the film festival.
* The idea was used for an episode of the Penn & Teller show Bull****!, in which they had self-proclaimed environmentalists sign a petition to ban DHMO.
* In March 2004, Aliso Viejo, California almost considered banning the use of foam containers at city-sponsored events because dihydrogen monoxide is part of their production. The issue was put on the agenda of the City Council after a paralegal found mention of DHMO online and did not realize it was a joke. The item was pulled from the agenda before it could come to a vote, but not before the city received a raft of bad publicity.
* Teams in a 2005 version of The Game circulated a petition to ban dihydrogen monoxide at Fisherman's Wharf in San Francisco, California--while dressed in superhero costumes.
