Run Flat Leakage
Does anyone experience leakage with the run flats on a C6 Corvette?
My left rear tire seems to always loose 4 lbs of air within a week and then settles down to no additional lose. I have measured it with both my tire gauge and the onboard sensor. Not sure whether it is the sensor or tire.

Get the nut on the sensor/valve stem checked. It takes a gentle touch but yet needs to be to spec and tight enough for the o-ring to seal. You probably shouldn't do it yourself until you know how. Good luck.

This was the problem I had with all four wheels. I tightened the valve stem nuts down and am no longer losing air pressure.

I have a problem with air loss on the right rear. It's very inconsistant, sometimes will loose 5 lbs, fill it up and it's fine for a week or so, then suddenly the alert comes on. The car had been parked for three weeks until last week, and when I got out of the driveway, the monitor advised only 17 lbs. of air... I will check the tightness of all the valve stem(s) and hope that fixes it....

Minor air loss can be attributed to radical changes in ambient air temps. For every 10 degree drop, you can lose as much as 1 lb. of air pressure. Periodic tire pressure monitoring is mandatory nowadays, even for the DDs out there. Avoids premature tire wear if nothing else.
