We were wheelin this weekend and I dropped all of my tires to 24 psi via a Currie tire deflater. Seems that I didnt have one of the stems put back in all the way and the left rear tire was leaking and when I checked it it was at 11.5 psi. The TPMS light never came on. At what psi does it come on?

Thanks

 

Should come on below 35. Your sig says 2007 Rubicon. The 2007's didn't come with TMPS.

 

Yes it is a 2007...well I suppose that might explain things them...????

I guess you really do learn something new everyday. So when did they start with the TPMS, 2008?

Man I feel stupid

 

Yes, 2008 was the first year they had it.

 

Wow, ok well thanks for the info. I feel stupid now. But at least I guess I know now

 

Spleify - don't feel stupid bro, this has been a learning experience for me as well lol.....Look at it this way - You got a JEEP -SWEET!

 

You sure it is 35psi and it comes on? That doesn't sound right to me.

 

Here are the stats for the TPMS pressures on a stock system.

Low Pressure OFF Threshold (PSI)

Translation for those of us a bit slow on the uptake?

 

I didn't think it was encrypted.

This is the legend:

The top number in each group is: Placard Pressure (Cold) (PSI)
The middle number in each group is: Low Pressure ON Threshold (PSI)
The bottom number in each group is: Low Pressure OFF Threshold (PSI)



28 (Tire pressure on the door post)
22 (Tire pressure at which the light comes on as the pressure goes down)
26 (Tire pressure at which the light goes out as the pressure goes back up)
