it's weird cause i have the stock 17's, and i don't remember hitting any potholes hard enough to crack a rim... but i still have to put air in the tire like every other week... happen to anyone else?

 

Have you tried the soap bubble test to see where it's really coming from. Could be the valve stem, could be a nail...

 

I have the same problem!!(SAME wheel too) I just noticed it the past month, I have to keep filling it up every other week or so and when I try to check the pressure with a digital reader, it wont give a reading (the guys at the oil change center tried too and could'nt) so maybe the valve stem is faulty?

 

dont use the digital...it is never exact. however it is highly doubtful that you guys have a rim leak (too new of a car,no rust or build up) UNLESS when the tires were being put on they broke the bead of the tire. could be a valve leak. spray some windex around the valve see if it boubles. other than that it must be a nail. you might not see it,coulve punctured the tire and fell out,or fell in.

 

I had this problem with mine before. For awhile, I would put air every week. Then one day I was coming home it was fully flat and I just put air on it a couple days ago. Eventually it just got worse and worse, so I tried to get it repaired. I later found out I had two nails on the tire and my sidewall was shot for having running it flat. I suggest you go have it looked at before you damage your tire.

 

Its a bit of a co-incidence that we both have the exact same problem, the exact same tire is'nt it. And the tire exhibits identical properties it seems, but yea should get it looked at

 

check and see if there's a nail or something first? if no, bring it back to Nissan

 

You could have driven over glass or a nail and not have felt anything. Who told you that a tire could only be puntured by hitting a pothole?

 

my guess would be a nail too. did it a couple times. that would be the first thing i would check out.

like dave said, i covered the tire with soapy water and look for bubbles. actually, another time, i took off the whole tire and submerged the tire in a metal tub full of water and looked for bubbles that way. it was more of a pain in the butt, but it was easier to spot the leak. then i just took the tire in my truck to have it repaired.

 

yea, it's probably a nail or something... i was just making sure there wasn't a recall/tsb or something i don't know about...
