Got new tires from Sams club installed and now after 2 days one tire is showing 23psi where according to tire gauge it is 35. Orange error display on the display.

please help.

 

Haven't experienced this.

I would try lowering the tire down to 20 psi or so then fill it back to the target pressure and see if that helps. Otherwise call or visit the installer and have them make sure they didn't damage the sensor.
