I wish my truck...

Didn't require a tire refill to 70 pounds to turn off the tpms light if the rears fall below 55 psi.

Ok seriously:
- Bigger fuel tank
- better offset on stock rims for 35 and 37 inch tires

Add spacers. Cheap and simple.

It's been reported you can set the tire fill alert preset to a lower value and this will stick the TPMS threshold.

You may have to start with a no code set condition.

I just got nailed by that. No way to clear it with AlfaOBD? I know you can change the thresholds if you have the PIN.

You don't need a PIN for the 4.5 gens. But yes, you can lower the threshold with AlfaOBD and the warning goes away.

As Brutal mentioned above, some have reported you can also lower the threshold through the Uconnect without even using AlfaOBD.
 
I was able to do it with alphaOBD. For my Power Wagon I set the threshold to 40.

Do you have the selectable tire fill app on your uconnect? You have to delete your old presets and make a new preset and it seems to keep the truck happy at 55psi

I don’t see it on there website. But looking at my tailgate, I don’t see why the one for a 2018 wouldn’t work.. I’d be tempted to try it.

Is this a real thing? I’ve never heard of a selectable tire fill app?

See pg 228 of owner manual for more in depth explanations. I haven’t used it to fill the tires but I set the threshold to the lowest on each tire and it seemed to work for me
 
I have set the 'TireFill' when changing air pressure, but it did not over-ride the main code tripping when below 55.
I don't see anywhere on my Uconnect app that would let me change anything related to tire pressure.

Is this a phone app or are we talking about a uconnect app?

It isn't really an app. It is a setting within the Uconnect.

First you enable Selectable Tire Fill.

That then allows you to enter the newly enabled menu and set one or two presets.

 
"selectable tire fill app" is this something that can be turned on with alphaOBD?

Update: found and added it, now shows up in my Uconnect!
