Well, I own a 03 350Z, Since I bought the car, I had changed my driver rear tire twice in the last 4 months. Last 2 months, the tire pressure on the same tire goes down everyday and I am tired of always putting air. Sometimes the tire pressure for all the tires is down... I think Im going to need an aligment soon but is this problem happening to anyone here, I dont want to change the tires yet if the problem comes from something else. Im tired of changing the tires and they only last a month or 2 before the tire pressure goes down everyday.

Any suggestions would be appreciated it....

 

If you are experiencing uneven wear, I would like to see photos.

If the tires are leaking air, umm, fix the leak.

 

sounds like it's your valve stem to me, and that sucks b/c thetire pressure monitor stems aren't cheap.

 

Reseal the tire.

Maybe there's a worn out TPMS nut and/or bushing.

 

oh damn, car is still under warranty so Im thinking they'll take care of it.
Im going for my 60k service soon, Im going to explain to them the problem, but usually some of those mechanics think that I dont know what im talking about.

 

Do you drive 10,000 miles in 4 months? You need to give us your milage before you panic about your tires being a problem.

 

I drove about 8k in 4 months....

 

Maybe the wheel itself is porous/

I had this on a Volvo alloy. I had an innertube fitted to see if it was the prob and the tyre never lost air after that.

Not sure if fitting an inner tube is cool on a 350 though!

 

Yea, I don't think I'll do that on the Z.
