Are there low pressure TPIS warnings on a 3500?

[JPM]

Are there low pressure TPIS warnings on a 2017 srw 3500? If so can I change them ?

 

[gsbrockman]

There is not. TPIS stands for Tire Pressure Information System. All it does is simply display the pressures from each wheel, without nagging you if one is too low based on a predetermined threshold.

Wasn't TPMS standard on all vehicles in 2017?
Mandatory by law.

Only for under 10k GVW

Only for under 10k GVW

10k and under! Class 3 starts at 10,001 lbs.

As already stated, nothing to set just shows the pressures and no warnings on the 3500's.

The 2500's do have a preset minimum pressure but it seems that it can be worked around with some time, effort and investment. Thread on here some where about how to do it and what it takes.

I think it would OK to be able to set a minimum alarm , but it looks like it cant be done on the 3500's

You are correct it is 10k and under but rule has no reference to Class 3 or any other class. It just states GVWR of 4536kg (10000 pounds) or less. Under 10k was close enough for the discussion at the time.

I haven't tried it but I would think it could be done with AlfaOBD using the same basic procedures that are used to set monitor pressure and switch a 2500 to TPIS. IE set the pressure thresholds, set to TPMS mode in BCM and then reset RF hub.

That sounds good, but I would have to find someone to help me with an AlfaOBD ,( tried before but couldn't find anyone)

 

[lpennock]

There are a couple of people on this thread that have it. Why kind of help do you need?

 

[JPM]

I was trying to get daytime running lights and the tire thing, maybe more?

common sense!

Daytime running lights is easy. You enable in BCM. Do you have AlfaOBD already?

 

[JPM]

Is there an upper pressure read limit on the 3500 sensors?

Is there an upper pressure read limit on the 3500 sensors?

I have easily seen 92or 93 psi on my 2014 RAM 3500......but I cannot answer if there’s an upper limit or not.

Common sense ?? If you are not staring at the screen , and you are losing air, there is nothing thats going to tell you until you have a flat tire. It makes sense to me to want a low warning. We certainly want the TPMS on our fifth wheels.

I haven't yet looked in AlfaOBD to see if I could add a low threashold for TPIS, but I have heard of people tuning their TPMS setting OFF vs lower... so it might be possible.

Based on how I use my truck I would have to set the warning so low that it wouldn't do much good loaded up. I run pressure in the 25 range while hunting, or if I have to put chains on and I don't want a warning for that. Besides that I have heard the lowest threshold for the 2500 TPMS is in the 30's (36 comes to mind??).

I have also seen pressures in the low-mid 90's without any warning.

I prefer to drive with the tire pressure screen up anyhow, so not having a low psi warning doesn't bother me. Not having TPMS was just one of many reasons I was 3500 shopping vs 2500 shopping... of course that was before I knew about AlfaOBD.

I prefer to run with the screen monitoring the coolant, oil, transmission etc. All I care is that one of my tires is not losing air, just a low pressure warning would be nice, and a setting that "I" could set.

Not too concerned going down a dirt road hunting, yes I lower mine for certain things like hunting or chains. My concern is traveling 65-70 mph with a fifth wheel in tow, and the only way I know what my tires are doing is if I am staring at a screen all the time or frequently hoping I catch it going flat. Yes a warning would be nice, like we have with TMPS systems on our trailers. Only got to have one tire failure on a heavy fifth wheel ONCE to know the importance of getting a warning about what a tire is doing, short of a blow out, they are great to have.

What I am going to do is just add the sensors to my truck, so my TST that I got for the my fifth wheel will give me a warning . Should of done it in the first place. Can set for whatever or just remove when not needed.

Considering that 1/2 the numbers on that page are fake I rarely look at it. Coolant is an actual gauge, and I put trans temp as one of my selectable gauges.

I’ll be getting a TPMS for my 5er, but if I could see trailer pressure on the dash I wouldn’t need warnings. Just my 0.02.

If the driver could set the threshold thru the EVIC that would be great. My 07 Tacoma had a warning set button that worked down to around 25. It was pretty nice.
