Today after running an errand, as I was driving home, the front right tire pressure monitor started giving a low pressure alert, showing 21 psi.
I hurried to a near by gas station to try to fill up (and hope that it will last me the trip home, knowing our Bolts have self-sealing tires).

Drove about 35 miles home, the pressure held! I jacked the car up, looked all around the tire .. nothing ..

now 3 hours later .. pressure seems to hold.

Anyone had this happen to you ?

I have not but thanks for posting. If that was a puncture and they worked that's nice to hear. Hope it wasn't anything else.

Perhaps you are the first person to test out the self-sealing feature of the tires! :cool:

Or a much cheaper option elsewhere! Just picked one up this week, along with a TPMS safe can of fix-a-flat, in preparation for possibly reducing some unsprung weight. Still haven't decided on summer tire choices...

hmm no nails that I can see, and after a weekly trip where the Bolt was just sitting in the garage, pressure held.
almost like a one-off leak .. badly seated valve stem ?
You could have run over a nail that was in something else (like a board), so it wouldn't have seated itself in the tire, just left the hole behind. I don't know how fast these self sealing tires work, I assume it is dependent on hole size and location. However if it is anything like running tubeless tires on MTBs you can lose a decent bit of air before it seals and stays sealed.
