"Check Tires" alert yet Current Pressure looks fine

[shayman]

I recently started getting a "Check Tires" alert. After adding air to the requisite 32 PSI (while tires were cold) and then driving around for a bit, the "Current Pressure" section on the dash shows all tires to be 32 or 33 PSI. But I'm still getting the "Check Tires" alert. Is there something that I need to do to reset the alert?

I had gotten this alert earlier in the year on a different tire and all that I needed to do was to add air to the tire and the alert went away.

Thanks

You can get it to recalibrate by selecting a different tyre (in PCM) and then going back to what you have installed....but...

There's a possibility that running pressures too low could contribute to the inside 1cm edge wearing to the cords prematurely. I think 32psi is too low in this case...

You are correct - I'm running pressures too low. I made the mistake of comparing tire pressures between the tire that was alerting with the ones that weren't. According the Porsche app, my tires should be at 35 psi. Once I got all of my tires to that pressure, the alerting stopped.

Thanks

Check pressures still.

On my GTS ST the lowest values are 38/42 iirc.
