19.5" tires are too thick to allow tire pressure sensors to read

[JPM]

I am trying to get normal tire sensors to activate and read on my 2017 3500 truck's dash. It appears that the 19.5" tires and Rickson wheels are too thick to allow tire pressure sensors to read or activate. Has anybody tried this and found a solution? I guess I could go aftermarket screw on the valve stem sensors and a separate monitor, but I would rather not. Any recommendations?

I have Ricksons 19.5 and dont have a problem. Well, I didnt put them in this time around but I had them in the last set with no issue.

I have Rickson forged aluminum wheel with commercial Toyo G rated tires that have very thick carcasses.
I used the internal mounted Dill TPMS 10 sensor trailer system for both my truck and flatbed trailer.
It also came with an extended antenna for the trailer sensors but I have never needed to use it with the monitor the cab.
Dill is oem manufacturer for manyTPMS sensors.

Is it too bold to suggest that something other then the wheels is the problem??

You have an aftermarket system if I am not mistaken, I would like the factory RAM OEM system to read my pressures in the 19.5's as the factory wheels/tires that came on the truck. There might be something the techs have not seen and I will continue to pursue it and report back.If I cant get the factory system to play with the Ricksons and the Toyo M 608Z 245/70R19.5 136/134N H 16 Ply tires, I have determined the aftermarket system I would like to find that is;


Is super reliable , no electronic gremlins,
Long life batteries in the sensors ,
Flow through sensors mounted on the stem, outside , (ability to add/lower pressure with removing the sensors)
a display that shows all four tires at the same time, no scrolling required
fast refresh rates on pressure( temp is welcome to)
Blue tooth capability to my smart phone for a display( not a deal breaker)
ability to read to 150lb( need to read to 120 but ...)

Link to the system you purchased would be appreciated as I’m interested...

Those will not fit my forged Ricksons, the valve stem is too big, mine have a hole size of .390" - 25/64"

These are what fit my wheels and there are no TPMS systems that size

Couple of questions...
What pressure were you running with the stock tires?
What pressures are you running with the 19.5's?
Did you use the original stock sensors or buy new ones? <- if new, this is the problem
If you used the old ones did they go back in the same corners?

Not apples to apples but when I changed sensors on my motorcycle I had to do one at a time, let the system learn the change then change the other one.

What pressure were you running with the stock tires? never ran the stock tires with the camper, so pressure are below the max @80psi
What pressures are you running with the 19.5's? 100psi on the back axle and 80 in the front at full load
Did you use the original stock sensors or buy new ones? <- if new, this is the problem, bought new ones -oem replacements, not going break down the originals
If you used the old ones did they go back in the same corners?

You are going to have to go to the dealer to get the new tire pressure monitors initialized. Each TPS has an electronic serial number, your system knows about the stock sensors and which corner they were on. It knows nothing of the new ones.

Working on it, but I am afraid the tires are too thick to have normal RAM compatible sensors read , activate, or be used.

No thats nonsens, they work as good with any tire.
The signal goes through the tire end the entire vehicle to the receiver. They are sure strong enough for 1/4" more rubber.

Next week I hope to get to the bottom of this and will post my results. That would be great if the sensors would be able to communicate with the truck.

I can’t imagine they won’t transmit thru the tire, but the single ply steel sidewall may block more signal than LT tires.

As far as aftermarket I have a TireMinder i10 and really like it. It doesn’t meet all your criteria but it does most. I didn’t want flow-thru senders as the centrifugal forces are pretty high on them.

Are you using existing 3500 style sensors? What is the valve stem bore diameter on your current 19.5’s? What about utilizing OEM 4500/5500 sensors for TPIS?

My OEM 20" wheels have factory installed sensors and work fine( not removing them and they wouldn't fit the ricksons anyways). The valve stem holes on my forged Ricksons are .390", and we tried sensors strapped to the centers that are readily available that were supposed to work, but we cannot get them to activate , through the tires, ( right after the bead in the side wall area I am guessing they are about 1"+ thick.)

More to come......

Do you know where the receiver(s) are located on a 2017 3500 srw?

In the cab? Under the hood ? Next to the wheels?

WCM Modul, also known as SKREEM at the steering column.
Are you sure your aftermarket sensors are using the right frequency for the RAM?
And are they activated, they are in sleep mode right out of the box.

Wow that's a long way through the truck for the sensors to send an signal! Is there an antenna(s)?
We couldn't activate the sensor through Toyo tire, so we thought of removing the wheel/tire from the truck, breaking the bead and trying to reach into the tire with the activator to get the sensor "awake" . (The tire guy probably should have activated the thing before mounting the tire, but never thought of it being a problem.)Then remounting everything to see if that works.( as a experiment , so far I have only one tire/wheel complete as the sensors and mounting is very expensive)

 

[gsbrockman]

What frequency are the OE sensors in the 20’s? What is the frequency of the ones you purchased for the 19.5’s?

I was kinda under the impression that the TPIS was part of the RF Hub module, and it’s located on the back wall of the cab. I could be totally wrong though, too....
