Yet another TPMS thread. With a twist. I think?

Anyways long and short, 2020 ram 3500 Laramie. Swr. 6.7, i changed out the stock Goodyear for a set of Cooper`s which were holding up fine so far with 20K on them so far,

my area got a bit of snow (i live on Vancouver island BC) which isn’t that norMail, , leaving a parking lot, was a bit rough, see, local plow operator forgot to put blade down i guess..lol, anyway, for the last year, my sensors have been fine reading the pressures and displaying on the dash, , tonight, well, no

hit a bumpm, truck shuddered like i drove over something, didn’t think anything of it, but thought to check my pressures on the screen low and behold. Back right is dropping, weird, held at 45. **** it, ill get off the road i think, no warnings on the dash at all, looked down, and done, 5psi on the shoulder …swapped the tire out and headed home

now the question, do the sensors not set off a warning or some such to say hey, pressures dropping dummy, pull over now kinda thing?,

i have a pic showing the other 3 at proper and the flat one, well at 0, , is there a setting somewhere I need to change out so i get a warning ??

Should be a chime as well as the little yellow warning light if the pressure drops below the threshold. Weird it did not go off. Can't see how changing the tires would have had any effect being the sensors still read the proper pressures.

Has your yellow warning light ever gone off in the past? Where I live when cold weather hits, the pressures drop and usually triggers the light. Just curious if it ever came on for you in that case. Just had to add air to mine. We have had a swing of about 35 deg F. Was running on the low end of the pressure range so the light tripped when the temps dropped.

3500s have TPIS, not TPMS.

It will show you tire pressure, but not alert you. You can enable TPMS with AlphaOBD

How do I get notified of a tire is low pressure?

2021 3500 Limited Dually. If a tire is low, or goes low while driving, how I'm I notified? Just an idiot light? Do I get a single chime, or multiple chimes? I tried to test this. In the driveway. Filling the tire, the tire monitor displays quick and accuate, and the Auto Fill Alert is a cool...

^^^One of the reasons I ordered a 3500 instead of a 2500.
3500s have TPIS and don't have TPMS with the annoying warning chime & orange light on the dash if you want to run less than 60PSI Front & 80 PSI Rear.
