Most of you seem to keep your tires around 34 PSI, that won't keep the low tire pressure light from alarming ?

There have been mixed results. Mine won’t alert until I get below 30. Others have reported higher numbers. You can always use a Tazer to lower the threshold or disable the alert altogether.

I set 33 cold on my stock A/Ts. I agree, 30 is the trigger for the warning. Hit it a few times when the weather was cold.

I had a bit of wandering at high speeds until I took my Moab to my favorite tire retailer. He Che key my pressure and said the dealer put 41 psi in all of the tires. I changed wheels and tires. He said the put 35psi when cold. I went straight to the interstate and the wandering was gone as well as the harsh drive. No problems with psi alarm.

I think the door jam says 36 cold, no lights going on and all is well, just like the book says!

Go Jeep!!!

I run 30psi cold. The Jeep handles and rides much better, on-road and off, than as delivered. Might have lost a MPG from 36, but I’m good with that.
I don’t mind the notification that I’m running low pressure each time I start up. Actually, I like it as a check.
Mine is very accurate.
It’s only one click from there to my screen of choice.

I run mine at 32 warmed up, it’s 28-29 in mornings, so I set alert to 25 with tazer. Never heard from it since.....:)

trigger point for stock calibration seems to be 30 psi - anything below that will trip it.

Drop mine down to 36 from dealer set of 42. Rides and handles much better.

For some reason mine is set to default of 37 (I have tazer and have not changed it) and yet my tpms blinks when car comes on and then stays on. Tire screen shows all pressures over 40 after warmed up and always over 37. Yet the tpms will never turn off. Any ideas?

Did you ever get any follow up on this? I just but aftermarket wheels/tires on and all 4 tires read 38psi but the dummy light came on.
