Let me be more specific....I run my dually at 80 psi with no TPMS. My moms ram has the TPMS.....with that said the sticker is rear @ 65 and fronts @55 but her tires are branded @ 80 psi max. I filled the tires in the rear to max psi and the TPMS sounded the alarm...took a minute to figure that out. A simple mistake...that is the information I'm trying to get out there.

Moms rig, Specifically, a dually? If so that doesn't make sense. I've run plenty of newer 2500/3500 trucks at 80 psi cold. Pressure will get close to 90 under the right conditions.
Even a 2500, the min psi is like 65 and the tire alarm goes off for low pressure.
Not normal. Something wrong with the truck.

All I can say is this thread, not unlike others is full of lack of or mis information.
TPMS are only re programmable with aftermarket software. Used to be with OE diagnostic software but not anymore.
1 tons don't have tpms. They have TPIS.
No HD trucks should, throw a high pressure alarm especially below 80 psi. I'm not certain they can at all. But never had one over 88-90 psi. But have 1/2 tons at 60-70psi that don't throw a high pressure alarm.
And "I just run what's on the sticker." Is like saying "I don't question what that Doctor is telling me. I do t understand it but he must be right because he's a doctor!"

Can you explain TPIS? I have understood that to mean an inflation system. My one ton truck only monitors tire pressures.

If you have seen one inflation chart for a particular size tire in Load Range E, you've seen them all. I've compared the inflation charts for several brands and they all have very similar, if not the same numbers on them.

So even if your tire's manufacturer doesn't publish one, you can usually find one from another manufacturer.

Of course if you can't weigh your truck conveniently, the tire inflation chart does you no good. It's also tedious to be constantly airing up and down every time your load changes.

There is nothing wrong with or misinformed about airing up to the pressure on the door sticker, so long as your tires are the same size and load rating as is shown on the door sticker. That gives you maximum capacity for the truck. You won't get a perfectly even wear pattern if you're not loaded to maximum, but you won't be underinflated for any load you happen to put in the truck.

Don't know what you are driving, but here is copy from my 2017 Ford manual.
I know, I know ... reading manuals is not popular thing.

Performing the System Reset Procedure - Single Rear Wheel
Read the entire procedure before attempting.
Drive the vehicle above 20 mph (32 km/h) for at least two minutes, then park in a safe location where you can easily get to all four tires and have access to an air pump.
Place the ignition in the off position and keep the key in the ignition.
Cycle the ignition to the on position with the engine off.
Turn the hazard flashers on then off three times. You must accomplish this within 10 seconds. If you successfully enter the reset mode, the horn sounds once, the system indicator flashes and a message shows in the information display. If this does not occur, please try again starting at step 2. If after repeated attempts to enter the reset mode, the horn does not sound, the system indicator does not flash and no message shows in the information display, seek service from your authorized dealer.
Train the tire pressure monitoring system sensors in the tires using the following system reset sequence starting with the left front tire in the following clockwise order: Left front - driver side front tire, Right front - passenger side front tire, Right rear - passenger side rear tire, Left rear - driver side rear tire.
Remove the valve cap from the valve stem on the left front tire. Decrease the air pressure until the horn sounds.
Note: The single horn tone confirms that the sensor identification code has been learned by the module for this position. If a double horn is heard, the reset procedure was unsuccessful, and you must repeat it.
Remove the valve cap from the valve stem on the right front tire. Decrease the air pressure until the horn sounds.
Remove the valve cap from the valve stem on the right rear tire. Decrease the air pressure until the horn sounds.
Remove the valve cap from the valve stem on the left rear tire. Decrease the air pressure until the horn sounds. Training is complete after the horn sounds for the last tire trained, driver side rear tire, the system indicator stops flashing, and a message shows in the information display.
Turn the ignition off. If two short horn beeps are heard, the reset procedure was unsuccessful and you must repeat it. If after repeating the procedure and two short beeps are heard when the ignition is turned to off, seek assistance from your authorized dealer.
Set all four tires to the recommended air pressure as indicated on the Safety Compliance Certification Label, affixed to either the door hinge pillar, door-latch post, or the door edge that meets the door-latch post, next to the driver seating position or Tire Label located on the B-Pillar or the edge of the driver door.

Performing the System Reset Procedure - Dual Rear Wheel
For further information see Understanding Your Tire Pressure Monitoring System and refer to Dual Rear Wheel, earlier in this section.
Read the entire procedure before attempting.
Drive the vehicle above 20 mph (32 km/h) for at least two minutes, then park in a safe location where you can easily get to all six tires and have access to an air pump.
Place the ignition in the off position and keep the key in the ignition.
Cycle the ignition to the on position with the engine off.
Turn the hazard flashers on then off three times. You must accomplish this within 10 seconds.

If after repeated attempts to enter the reset mode, the horn does not sound, the system indicator does not flash and no message shows in the information display, seek service from your authorized dealer.
Train the tire pressure monitoring system sensors in the tires using the following system reset sequence starting with the left front tire in the following order: Left front - driver side front tire, Right front - passenger side front tire, Right outer rear -passenger side rear outer tire, Right inner rear - passenger side rear inner tire, Left outer rear - driver side rear outer tire, Left inner rear - driver side rear inner tire.
Remove the valve cap from the valve stem on the left front tire. Decrease the air pressure until the horn sounds.
Note: The single horn chirp confirms that the sensor identification code has been learned by the module for this position. If a double horn is heard, the reset procedure was unsuccessful, and you must repeat it.
Remove the valve cap from the valve stem on the right front tire. Decrease the air pressure until the horn sounds.

I think Gritdog is suggesting it’s information system. In other words, displays the pressure but with no warnings.

Thanks Kayteg, that’s re- setting or re-learning. Not adjusting the thresholds. Reading the manual is only half the battle.

On edit you may have meant adding air to tires not adding “20psi” to the sensor threshold (which 1 tons don’t have threshold anyway).
Either way, every tpms or tpis system I’ve been around, including a handful of fords too show pressure chenges in real time or nearly real-time and no re learn process is needed under normal operations. Newer vehicles like yours don’t even need re learn when fire position is rotated.
Keller May likely have something wrong with the system that a reset or re learn may fix but probably not the case if it’s already reading the right tires. Worth a shot though, you’re correct.

Worktomuch Jim H explained it accurately there.
