2023 with NO TPMS

[JBoo2911]

My Ram 5500 SLT Cab Chassis does not have TPMS (Tire Pressure Monitoring System). I was pretty annoyed after getting the truck to find this feature was missing in my ‘23. But my brothers ‘22 Ram 2500 Tradesmen has it.

Everything above a 2500 has Tire Pressure Information System (TPIS) instead of TPMS. It's the same thing, but doesn't alert on low pressures. you can change between the two with AlfaOBD if you so choose.

o ok, cool. But what is AlfaOBD?

It’s a program for making configuration changes on Stellantis/FCA/etc vehicles.

It’s useful for things like I mentioned above, as well as for adding features your truck didn’t come with, recalibrating for tire size or axle ratio changes, and a whole host of other things.

See the thread here for more info on what you can do with it:

AlfaOBD

Has anyone played with AlfaOBD on their 2019 HD's yet? I'm curious if anything is accessible to "change" and if it just works. There is lots of different info out there on other forums, but i haven't found anything in regards to the 2019's. EDIT: AlfaOBD does work, here is the what is needed...

@JBoo2911 - Did you get this figured out? I have a 2022 5500 and have no screen showing tire pressures, though I thought this was a standard feature on the SLT trim level.

 

[JBoo2911]

I was under the impression my SLT would have TPMS as well. We don’t, as a hot shot driver having this feature sure would of been nice!

According to this we have TPIS (which is basically TPMS without a warning chime if there's an issue) as a factory option. This doesn't seem true though as I have no tire information screen.

Yea on my 2019 5500 there's no Tire Info Screen either.

My brother just bought a 2022 Ram 2500 Tradesmen and his truck has TPMS tho….

Pretty sure everything considered a consumer vehicle is supposed to have it by law. I don't think the commercial cab & chassis are required to have it.

Can the 2500s switch from TPMS to TPIS?

I seem to remember seeing that you cannot switch 2500s but not sure.

Yep!
