TPMS: What's the latest?

Not all of us have trucks with the latest and greatest. :) My 2001 didn't come with them.

My 2014 , does tell me air pressure if I go to that screen , but there is no warning on the Ram 3500, so if I am not in that screen I wouldn't know if there was a low tire . The 2500 Ram trucks do have a warning ,not sure why the 3500 does not . The newer ones may, I don't know .

On a trip towing the fifth wheel, I will go to that screen ,and look at air pressure quite frequently .

Not on my 2000 either. ;)
I have a Tire Minder and really like it. It is the valve stem cap type, so I agree, I don't think the temp is very accurate.

An '18 Chevy Dually doesn't have Factory sensors either. I believe SRW does.

I think 2008 is when they became mandatory. My brand new truck won't tell me PSI unless I go into that screen either, but it will show a warning light on the dash if there is an issue. Showed up one morning when the air temp dropped from 70 to 30.

TST 507 cons:
Small screen
Dim screen in bright light
Can't be turned off when USB cable is connected
Display graphic is OTR truck related. Would like a RV related graphics
All axles on a trailer use the same high/low psi settings (individual trailers can be different) and while OK for my toad there might be reasons for some toads or towed trailer to use different axle psi settings.
TST won't come clean on lower temperature readings than the actual internal tire psi, I called.
No explanation as to why they recommend not changing the axle temperature settings, perhaps related to the above.
Sensors are expensive $50

Pros:
It works well
Cap sensors are lighter but require removal for filling the tire, the lock nut is easy to loosen, stays on the stem and easy to retighten. Highly doubtful the nut would prevent theft
They claim rubber stems are OK but I suspect longer RV rubber stems would be a issue. My toad has TPMS and I have not found any metal stems with TPMS for it (for towing)
No problem with sensors on my toad as expeceted since multiple trailers are supported.
Sensor batteries are easy to replace

Note: There are older sensors that have a more involved lock mechanism and have 3 small screws for battery repacement. I don't have these so maybe someond can clarify.

To me the biggest con with the TST system is the fact that it takes about an hour before you're notified that a sensor has lost contact with the monitor. Seems excessive to me.

The difference with Ram at least on my 2014 3500 is it has no warning or light come up on the dash. Ram 2500 does .

Odd. Seems like a warning light would be required. Why have a TPMS if it isn't going to alert you to a problem?

It is odd, especially since the 2500 does . I can air my rear down from 80 to 45 when not towing ,and there nothing, other then looking at the screen to check air pressure .
