Good afternoon I am a new member (just registered) who was referred to this site by one of my colleagues. I have taken my new Jeep (2012 Grand Jeep Cherokee Overland Summit) to the dealer because of the tire pressure on more than 3 occassions to date. Is that normal?

What do you typically use for PSI? Folks at high altitudes sometimes have to run 1-2 psi above recommended gauge (37 to 38 in this case) to keep from false TPMS readings. I don't think any manufacture does this, but they should use a fifth sensor to measure ambient pressure so the TPMS reading can be adjusted to gauge pressure.

I check it in the morning before driving, and stick with 33psi. The manufactured suggested psi. I refill in the winter months more often than summer. In the coldest of winter, -10 to 25 deg., i have to drive for several hours before it resets the tpm, but not worried about it because i know the actual meter reading is correct vs the tpm. In the summer it has no problems at all.

So 33 psi is whats recommended on the door sticker for your model? Mine recommends 36 psi. And the warning goes off when the TPMS reaches 30 psi, which is 32 or 33 psi gauge at your altitude.
