Quick Question About Air Pressure In Tires.

I am going through your CDL Training (Thanks for that by the way. Feel like I'm getting a great headstart before even going to actual training.)and just went over the part about checking your tires during hot weather driving as high temperatures increase air pressure. I currently work at a Honda Dealership and they fill all the tires with Nitrogen. The claim is that it provides more stable tire pressure in hot or cold weather conditions. Is this something companies are starting to do with their trucks and if so, does it seem to actually make a difference? Thanks.

Nope just air we check tires everyday with a tire guage that's why its important to do a pre trip mid trip and post trip insp.

Okay, thank you sir. Was just curious and I appreciate the speedy reply.

Nitrogen.....is that flameable at any temp ?? I can see why they use it, but I have never even heard of it before.....I really need to get out more..

I've only heard of it being used in the arctic for the bahaing they do up there for when I tires falls off the bead a match puts it back on.

Rebel...thats just plain scarey !!!!!

No, Nitrogen will not burn at any temp. That is another use for Nitrogen, to keep oxygen away and slow down decay. Air is over 70% nitrogen.

It's evidently not super new with "four wheelers", (I love that you guys call a car that! lol) as almost all dealerships and most of the tire shops are going to it. Most newer cars are coming with tire pressure monitoring systems now and as I said, the big thing with Nitrogen is that it is supposed to be more stable in hot and cold temps. Theoretically it sounds like it would be perfect for trucks that are rolling all over the country. Just don't know if it actually works like it's supposed to or if it's just some fancy rhetoric to get extra money tacked on to the price of the car. lol

My wife and I are so dang excited to get on the road! First day of CDL school on April 8th and although that's less than a month away now I want to start tomorrow! Love this sight and appreciate all of you putting up with our giddiness! I bet you experienced drivers get a good laugh from some of our questions and comments sometimes!

Nitrogen IS more stable at extreme temperatures..it doesn't expand and contract with heat or cold like air does and it's also "drier" in that it doesn't absorb water like air. ALL high altitude aircraft use nitrogen in their tires. Think about it..a jet travels at 35,000 feet where the temperature is many degrees below 0, then in a few short minutes it descends, and lands whereby the tires have to brake hard enough to slow it to a safe stop...the temperature difference in those few minutes is incredible..from below 0 to probably over 100 degrees in a matter of minutes..the auto industry is finally starting to embrace this technology, but it isn't anything new..the only problem is supply..Nitrogen isn't something you can just get anywhere and it IS more expensive as it is a "manufactured" gas.
