    Exclamation Nitrogen in New Car Tires

    Ron, Or anyone for that matter,

    Just heard that some new cars are coming out with nitrogen as a tire inflator. This, I guess, is due to the stability of the gas in relation to the tire pressure sensors.
    What, if any, hazard is this going to present? (Especialy in fires)

    Looking forward to replies.

    Shouldn't be any danger, there is already 78% nitrogen in the tires anyhow.

    No danger at all. Unless you tried to breathe the air in the tire in some desperate attempt to survive being underwater....

    I just had a laff with my tech salesman the other day. He was trying to sell me a nitrogen generator."What do I need that for?" For filling your customers tires. Really? what leaks out of the tires? Oxygen. OK,what is room air made up of? I dunno. Well,it's 78% nitrogen,plus 21% oxygen and some traces,SO if the oxygen is what is leaking out then WHY do I need a nitrogen generator. He left.........muttering. T.C.

    Nitrogen is a dry gas as opposed to the air that comes out of a compressor which has a large amount of moisture in it. The moisture is "supposedly" a cause for tire rot from the inside. It's a marketing scheme and they really had no concrete proof of normal air being harmful to tires.

    Using an air dryer there will be a negligible amount of moisture in the air. In any event we won't be doing it any time soon. T.C.

    We had an auto a little while ago and the front tire blew no different then any other tire.

    It was only after the fire we found out they were nitrogen filled.

    So in a completely unscientific assumption I'd say don't worry about it.

    I believe NASCAR crews are now powering their air tools with 100% nitrogen, also purportedly for moisture management.

    I've heard that weeds will grow much faster with Nitrogen filled tires if you leave your car parked in a field for too long.

    nitrogen is inert gas not flamable and not expand and contract in heat or cold all safe

    Not ENTIRELY accurate. Nitrogen does expand and contract but at a lower rate than room air. That 22% other in a tire doesn't affect the AVERAGE motorist that much. Racers like nitrogen because their tires build heat QUICKLY and a Psi change in a tire can have a BIG effect on handling.For Joe Q Public.........Not so much. T.C.

    None whatsoever. (Aside from those associated with plain old air under pressure in tires anyway.)

    The Code is more what you'd call "guidelines" than actual rules.
