Actually yes it matters. I just verified with some of the engineers down the hall, one of which worked for Bridgestone. We also googled just to make sure. All of your measurements are PSIG.
Your springs and your TPMS measure the amount of pressure ABOVE ambient air, they then add 14.7 psi which is atmospheric pressure at sea level and give you a number.
- if there is zero force on the spring, you are exactly balanced with atmospheric, and your pressure is 14.7 psi

So, the springs in your deflators are going to reduce the pressure to your setting of X. Where X is a certain pressure above the current atmospheric pressure.

At sea level they reduce it to 20psi for example (6 psi above ambient)
And the same spring will reduce the pressure to 15 psi at 10,000 feet (approx).
Very insightful! It’s always good to learn more about these things. Thanks for clarifying and contributing!

My relatively cheap list:

All weather mats
Door sill guards
Mirrors for doors off
Lights (and mounts)
A bag of ducks 😁

And one to grow on…tires but that can be a pricy one.

Thanks. That makes a lot more sense than what others have stated.

Air tags (2).

I have a new JLUR that I am picking up soon. It will have 2 air tags hidden in separate locations. I had a buddy have two in his jet skis. Recently he had an axle issue, and the tow company brought a flat bed. He was able to tell that they stopped for too long, and called to ask what was up. It seems that the driver had the wrong address, and was in the process of offloading the trailer there.

I know nothing is fool proof, but I want as many cards in my hand as possible.

Door sill guards. Clear film works even better.

Front mud flaps if you don’t want the paint on your door hinges chipped.

Be aware that a stubby antenna will hinder reception.
Neoprene seat covers?
I have had Wet Okole on my farm truck, F250, from day one in Aug 2000. The seats still have the pile and combing

Removing the sticker that says Wrangler, I hate that name!!
And a Tazer
Isn't Jeep changing the name to Cougar. That's worse.
