Nismo Tire Pressure

fuct

ALSO NEVER GET AIR AT A GAS STATION!!!! there is water mixed in with that line. just spray air and you will see water come out too!

If they have a large air tank you are fine, the water separates from the air when highly compressed. If they use a small noisy compressor stay away.

Also, by the time you get to the gas station your tires will probably warm up enough to gain a couple of lbs of air..

So....just add 2 or 3 pounds extra....go home let cool off for 4 to 5 hours.....drain the water out......and let out air to the desired pressure...

So where does everyone get their tires filled up at? Would this mean that a home air compresser, which are small, also has the same problem?

fuct

not if it has a humidity/water catcher built in. usually a small tank off to the side.

define small compressor?

ChrisSlicks

Small compressor would be one that doesn't have a storage tank, i.e. portable tire inflater. A home compressor you would use with air tools has a storage tank and due to compression most of the water goes to the bottom of the tank (and rusts it out but that's a different issue), additionally it is very simple to add an inline water filter.

I normally use a compressor at home (18 gallon tank, got it Home Depot during a killer sale and this is about all I use it for).

My Z came with some BS nitrogen fill - does anyone know anything about this? I haven't had to add any air yet, but am curious as to what I should do when it needs it. The dealership is the only authorized dealer (can't remember which company it was) in the area and their make-ready is the only place to get a fill.

you can safely mix regular ole air with nitrogen inflated tires, however, the main reason nitrogen is used is because the molecules? (im no physicist) are larger, and thus dont leak out of tires as easily. at least thats what i remember from the one science class i took years ago in university.

so in essence...if you have nitrogen filled tires, you shouldnt have to really fill them, UNTIL you get an unnatural leak (hole in the sidewall caused by a nail for example)

FERRARI

Air contains roughly (by volume) 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases.
