Also:
Don't expect your tpms to be within better than five pounds or so of your Guage.
It's a religion on this forum to chase psi to the ounce.
The tpms is a warning device. It warned you of the 38psi.
It is not a tire pressure Guage.
Mine is off by five pounds. To some here that would be the end of the world and they'd sell their rv.
I know it's off five pounds. I'm looking for a differential between tires as a warning, not a confirmation of my exact tire pressure.
