Run Flat Question
Friday my gauges showed my Passenger Front Tire having 23 PSI and all other tires at 34 psi. I manually checked, all tires showed 34 psi (to include the front passenger). Next day, gauges displayed 15 psi in that same tire. Instead of taking it to the dealer for no reason, I took it to the local tire shop to have a visual inspection for any nails/holes, they came up with none and said that their manual tire gauge was showing no loss of air and it was at 34 psi. The dealer is a pretty far drive and I'm going to make an appointment. Anyone have suggestions? I'm thinking it could just be a computer glitch.
Do run flats keep the PSI pressure even with a defect? This is my second C6, I've experienced a nail in a tire before, but nothing like this.
Thanks!

Very occasionally, re-training the sensors will fix a problem like this. You might get the tire store to reset them for free, if that doesn't work you can have them install (~$100 parts and labor?) a new sensor. If under warranty, the dealer will be much cheaper.

A sensor problem if relearning doesn't work.

No run flats will deflate to zero pressure if they have a hole. They stay driveable because of the sidewall strength. This seems like a TPMS in that wheel, have it reflashed and if that does not do it replaced, the dealer should do all that under warrenty.

Since the car's still under warranty, I'd just let the dealer handle it. They'll probably just replace the suspected sensor, and reprogram them all. I swap to track tires all the time, and have a Bartech program tool. No such thing, as programming just the one, but the proceedure for doing them all, takes just minutes. If doing this yourself, keep the windows down, as tends to lock the doors. Also, run flat or not, all 08' up, have the TPMS system.
