Slowly loosing air pressure on one wheel (Rear Right)...suggestions?

[Jkim]

I have been to my local tire center, and they could not find a single leak. Not the valve stem, or the rim... And yet it looses pressure consistently. It takes about 10 days to loose half its pressure. ie 40psi on Monday, 20 psi on Wed (next week). So its a rather slow leak...but still a leak. Its only my Right Rear tire.

Is there anything i can do? Im completely lost....

Did the tire shop replace the valve core?

Well, If worst comes to worst and you're short on cash, you can try to take it somewhere to have the tires filled with nitrogen? its pretty cheap I think and its supposed to leak a lot slower than oxygen(if at all). but im not positive, someone please correct me if im wrong :P

have a shop take the tire off and put it back on, its only like $5 at Costco, I've had this sort of problem on 2 different cars, that solved it. Good luck, I know how annoying it is.

Same thing happens to me but mine is even a bit slower with 1/2 pressure at 15 days

Same thing drove me crazy; two tire companies couldn't find what was wrong. Put tire sealant as a last resort, still lost pressure, took it back to Michilin dealer - they finally saw bead was seperating, due probably to low tire-pressure driving. Very hard to detect, sealant leaked out and that's how they discovered verrry slight seperation. Good luck ...

Take it somewhere else.

I took it to firestone. They found an extremely small leak near the sidewall. Unfortunatly they said they can't patch it because its too close to the sidewall.

Is there anything i can do about this leak? I really dont want to spend 160 bucks on a new tire when i just got this set like 3 months ago.
