New Z Owners - Check your tire pressure

texmedic · 07-08-2009, 10:23 AM

Hey not to bring such an old thread but I got a low pressure light a couple weeks after getting the car and after researching I read that a lot of 350 guys [350 forum] had switched to nitrogen and the problem cleared up. I went to the dealer and it cost me 23$ for life time nitrogen which was reasonable, but a couple of days ago I got another low pressure light. Although I havent had a chance to check the pressure in the last 2 days yet, I was curious if anyone else has the recurrent light issue?

Ummmmm...Did you ever think you might have a leak? Nitrogen is not a cure for anything. Look for a Nail...You've got one in the tire somewhere..

I checked for nails when i switched to the nitrogen, but not since the new light coming on. thats a good call though!

FYI the big sell of nitrogen is safety related.
Mainly because it reduces the chance of driving on tires with dangerously low pressure.
Nitrogen molecules are much larger than oxygen, and cannot "seep" out through the tire rubber like oxygen does. SO... the tires stay properly inflated for much longer/indefinitely...

It may also be less affected by tire heating, but seepage is the main reason it gets "pumped" so much.

that was what I had read about the nitrogen. I wouldnt have thought about it except someone on a 350 forum I believe had written about similar issues and the switch had apparently cured it. I have noticed a little better mileage though. I gave the tires another once over for nails just in case { i thought checking the tires for nails and the like was sorta a given} and right now I'm working and dont have my guage with. I'll check the pressure tomorrow once I get home.
