Tire Fill Alert - Sport S model

[casualthursday]

Has anyone successfully used the Tire Fill Alert function on a Sport Model (not the STFA on the Rubicon).

I can enable the feature and can see the hazard lights come on indicating the system is working, however, my challenges are as follows:

1) The system doesn't seem to retain my preset of 35 PSI even when i exit out of the menu and go back in. I understand everything resets when the truck is turned off and on again.

2) Most importantly, I never hear the horn sound when reaching pressure. In fact, the TPMS seems way behind (I would be at 37 psi and the system is a few pounds behind).

Can anyone guide me through the process of point me in the right direction?

Use a deflator with a proper gauge, in my opinion. I didn't know these were available for sports, but even if they were I'd never use it because a valve-pulling deflator is quicker and more accurate.
