TPMS Issues

[mobo]

Hi, I own a 2021 RAM Rebel. I bought new wheels online and ordered TPMS sensors with them (not Mopar sensors though). After getting the new wheels and TPMS sensors on the system is recognizing the tire pressures but it moves the sensor readouts around randomly. For example, I show two tires with 55 PSI and two with 45 PSI, but they move around. The 55 PSI's don't stay on the front. They may show on the left side, then the right, then one in the front and one in the back and etc. Then the system will occasionally say "Tire Pressure Unavailable". What would cause this moving/jumping around problem

I am experiencing the same thing with a pair of cheap chinese senders from amazon. The other two OEM Mopar are rock solid, will order 2 more OEM and be done with it.

Wise choice, because here's what I found out late yesterday from a tire service center here. The tire guy said he called FCA and was told the aftermarket sensors (MAX Select brand) were the issue probably due to frequency differences. Sooooo......I went home and took the stock sensors off my old stock wheels and took them back to the tire service and they are currently swapping them back to the original sensors on my new wheels. So we'll see how it goes when I pick it up. If it cures the issue then hallelujah.
