What is the lowest safe tire pressure?
20 pounds per square inch
If you have standard passenger tires (ninety percent of vehicles do) the lowest tire pressure you can generally drive with is 20 pounds per square inch (PSI). Anything under 20 PSI is considered a flat tire, and puts you at risk for a potentially devastating blowout.
How much air should be in a jeep tire?
With a C range radial tire most Jeeps can run about 20-25 psi on the street. Most bias-ply tires can hold up a Jeep with about half that. Off-road I consider 10-12 psi a good starting point for a radial tire and I’ll often go lower than that if the terrain is really soft and there are few tire hazards.
What happens when an oxygen sensor goes bad in a Jeep Wrangler?

Where can I find the u0127 fault code?
If your scan tool can access fault codes and the only one you retrieve from other modules is the U0127, try to access the TPMS module. If you can access codes from the TPMS module, then the U0127 code is either intermittent or a memory code.
Why does my tire pressure monitor say u0127?
If you can access codes from the TPMS module, then the U0127 code is either intermittent or a memory code. If unable to access codes for the TPMS module, then the U0127 code that the other modules are setting is active, and the problem is there now.
