Question on Tire Pressure on C5 (2002)

Hi,

I have an 02 C5 coupe with run flat tires - last night when I started
it, the DIC showed the tire pressure in the rear left tire as low -
24psi. I stopped by a gas station and added air to all tires to make
them 28-30psi.

This morning when I started it, the DIC showed the pressure on the
rear left tire as low again - 23psi! Not sure if this is a leak - the
tire looks good and does not need replacing.

Any suggestions? I would prefer to avoid going to the dealer for this
if possible!

Run Flat tires will look fine even with Zero presure. That way you
can drive on them while they are flat.

Sounds like a leak unless you've been driving where there was an
extreme temperature or altitude change.

Then go to a tire shop that does Runflats. It should be patched from the
inside.
