Air pressure loss in tires
My 2003 with stock wheels and tires loses 1 - 3 psi per tire every week. Have never had this problem with any of the 5 other Z's I've had. Not talking about pressure going down when cold. This is a loss of pressure. Can't find any leaks. Is this something peculiar with low profile tires? Anyone have any thoughts as to the problem?

I was going to post something similar but I'll just respond...
I had the same problems with the stock Potenzas, it seemed I would lose air each week. As soon as I upgraded to some Kumho all season tires, this problem has disappeared. I only check the gauge from time to time, but I haven't aired up my tires since I had these installed last fall. Maybe you should buy a better grade of tire and see what happens.
Hope this helps....

yeah, all tires will lose air eventually. Just buy a small air compressor for your garage and you'll be good to go. I picked one up with a digital guage and auto stop at pep boys for like $40.

do you have a turbo kit? if you do, you might need to hook up the turbo to yoru tires, that way all that extra exhaust air can keep your tires going even if you have a leak. its nissan new run flat tire system.

The tech dismounted the tire and coated the outer lip of the rim with a chaulky substance to fill in all the pores. I haven't had a problem since.
They say the air we pump which is mostly carbon dioxide, a bit of oxygen and nitrogen will leak through some tires. The tire doesnt fully seal all the air, if you dont want your pressure to come down, you pump nitrogen like the big rigs do. Nitrogen stays inside the tire and doesnt leak out.

Heres a good article, http://www.findarticles.com/p/articl...15/ai_97872906.

In 1772, Daniel Rutherford discovered something that he called "mephitic air." We now know it as nitrogen. In 2003, David Connaughton has an idea regarding nitrogen. He would like to see every tire in America filled with it. Connaughton is national OEM manager of Parker Hannifin's Filtration and Separation Div. (Cleveland, OH], where, not coincidentally, they make nitrogen inflation systems. Connaughton says that as the pressurized air used to fill tires slowly permeates tire walls and escapes, it not only leads to underinflation, but the oxygen portion of the air reacts with the chemical bonds in the rubber, weakening it and reducing tire life. This can lead to a panoply of bad results, from poor mileage to on-the-road blowouts. Inflating tires with pure nitrogen mitigates many of these problems. It is an inert gas that does not react with rubber, so tires maintain proper pressure longer; and run cooler, minimizing the possibility of blowouts. Connaughton says that tires filled with nitrogen can last up to 2 5% longer, which translates into $100,000 in savings for a truck fleet of 50 with 900 wheel positions.
