Nismo Tire Pressure

Pelican170 · 11-09-2010, 08:43 AM

Hey Guys,

I happened to check my tire pressure this morning and the guage said my fronts were at 30 psi. I know the max. for these is 50 psi. Was curious if everyone fills them up to 50 or under?

The tire max is 50, but the manufacturer recommended cold pressure is 35. If you filled them to 50 you would be very unhappy with ride and handling.

I agree

Yea thanks guys. Found the manufacturer's recommendation on the door jam. 35 it is... I also think the tire pressure guage I just bought is crappy because the gas stations showed about 36, which is fine...

The gas station pressure gauges are almost always wrong, nice cheap digital gauge is the way to go.

This can be found on a sticker in the driver's door sill area

I get beat up as it is in my Nismo... I couldn't imagine having the tire pressure at 50.

I would also venture that a psi of 50 would create a less than flat tire surface, thus removing traction from the Z and causing inconsistant wear. You'd certainly burn your tires up at the line with over inflated tire pressure.

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?

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

define small compressor?

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.
