Anyone have a problem with the OEM RS 20 inch wheel ? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I have had my Camaro for about 3 months and since day 1 that I took it home from the dealer, the rear passenger side tire loses about 1 PSI of air per day. All the other tires hold the air fine. Both the TPMS and my own digital tire gauges show the loss so it is not just a defective TPMS sensor. I have brought the car back to the Chevy dealer twice to have it looked at and both times the dealer could find nothing wrong with the tire.

A week ago I had the OEM P-Zero's removed and Pirelli Scorpion winter tires put on and made sure the tire dealer put the wheels back on at the same locations so the TPMS would still report correctly. Sure enough, the rear passenger side tire is still losing about 1 PSI per day.

This leads me to believe the factory wheel is defective and slightly out of round causing the air leak. Is there any fix for this situation short of getting a new wheel ? I am assuming this should be coverd by warranty.

Try soapy water on and around the valve stem or it may be the valve core.

Thanks for the suggestion but I did have the Chevy dealer do the tests you recommended and they said the valve stem/core checked out OK. When I got the new tires installed last week I also got brand new valve stems. So with both brand new tires and brand new valve stems but still have the air leak, I think it is the wheel that is the issue.

Easy fix , take the wheel out from the car and DEEP THE ALL WHEEL ASSEMBLY in a big enough container filled with water and you will see with your own eyes were the problem is

There is a Cadillac TSB about their aluminum wheels having corrosion around the bead seal and allowing air to leack out. I had the same issue with my Camaro, so I printed out the Cadillac TSB and carried it to the Dealer. They broke the wheels down, found the corrosion, did the recommended repair and I'm not losing any more air. Just google Losing air pressure and the TSB should come up in the search.

My car had this exact same problem but it's with ALL the wheels. I had to constantly pump it every weekend. The weird thing is that it stopped doing it at about 3k miles.
