Does anyone know what the lowest tire pressure you can run and keep the low tire light off or a way to disable it.

I experienced TPMS warnings at 30 psi...I believe the threshold is set about 4-5 psi below the OEM tire pressure setting.

To get rid of all this you might invest in a ProCal Module from AEV.. You can set and undo all you want..and there is a lot more you can do with it as well..

Thanks for the info. I am just trying to get a better ride after I installed a 2.5 Teraflex coil lift.

I found that 32 psi on my Rubicon is the threshold for no light, so that is what I run. Factory pressure was at 42 psi.

I've had a different experience all together.. Even if one of your tire pressure is off by 3-4psi from the rest of the tires, it'll light up.. I had that problem till I went got it equally pressurized at 30psi.. Haven't had that problem since..

Well stated... pressure difference is very important as well....and have a good reliable pressure gauge...

Pro Cal says 29 is the minimum, but if it is chilly you will experience a light until your tires warm up. Had a light all winter at start up, 5 miles out the pavement, clear...clear all around, oh sorry went NASCAR for a second with all this talk about tire pressure

I have two sets of tire/wheels and the set I have on now, are my bigger Hankooks, no TPMS transmitters in the wheels, so there's a little "chime" when I turn the IGN key on

Yeah, but I thought his question was how low can you go without getting a warning

I believe the low AVERAGE temp is 32 psi, with no TPMS warning and thats not low enough, for a good ride with bigger tires

I run mine at 28psi and with tougher shocks , that makes for a smooth ride

They may have come from the dealer at 42, but the factory recommended psi is 37. 32 will most likely be the low threshold.

I have repeated the issue with different tire pressure, it will give you a warning even if above the minimum, same situation on Trailblazer
