How can the TPMS pressures be changed

[Badunit]

The TPMS systems were a result of the Ford Explorer/Firestone blowouts from years ago. The result was the TREAD Act, intended to protect us all from underinflated tires. The result for us pickup truck owners is the requirement to run with grossly overinflated tires when empty or to do our best to ignore the constant low tire pressure warning, thus defeating its purpose while also being an annoyance. Sounds like a typical government action to me: find a tragedy from which to create a new law then write the law in such a way as to make it an annoyance but without actually solving the problem (or, even better, while making the problem worse or creating a different problem).

Buy a 2013 3500. No TPMS.

Buy a 3500 or bigger Cab and Chassis.. I guess our wonderful ignorant law makes assumed that drivers of bigger trucks check their tires oftener??? But I am not sure if todays "Steering Wheel Holders" know what a tire gauge is???

Yep, be progressive and buy a 3500 as it just gives you a read out of tire pressure and does not alarm you! Some are alarmed by the slightest little issue! SNOKING

I actually like the tire pressure readouts on the EVIC. It is nice to be able to see my tire pressures so I can monitor for leaks when going down the road. What I don't like are the warning lights and the TPMS screen popping up every time I start my truck, regardless of what I was looking at prior to shutting down. In other words, I like the 3500 system better.

Love the term "Steering Wheel Holders", never heard that one but very descriptive... there are few drivers!

Yup, for all the potential electronic gremlins and emissions issues, the most common part to fail in vehicles today is the nut behind the steering wheel.

This is my only gripe with this new truck of mine.I had my dealer change the setting in the computer and it blows my mind that the software can't communicate with the light. He reprogrammed my computer to 50 psi for all 4 tires and all 4'tires are above 50psi but the low air light will not go off unless I air them up to the higher pressures. The tech aired them up and down I don't know how many times and driving it after each adjustment but he cannot get the light to go off. Reading my evic saying air up to 50 psi when all my tires are above 50 psi and the light being on is just stupid? They have to figure out a fix for this because it's being discussed on so many forums.

The mfg will not spend any time or money to circumvent a federal safety law

The law is a little convoluted and it morphed over time but the gist is this:

TPMS must warn the driver when the pressure in any single tire or in each tire in any combination of tires, up to a total of four tires, has fallen to 25 percent or more below the vehicle manufacturer's recommended cold inflation pressure for the tires, or a minimum level of pressure specified in the standard, whichever pressure is higher.

The tire pressures on the placard are the recommended pressures. There is no provision for light load pressures or aftermarket tires that require different pressures. Tire placard, period.

Stupid inflexible rules. Congress required TPMS systems as a part of the TREAD act and the National Highway Transportation Safety Administration wrote the rules. You would think a department with "highway transportation" in its name would understand trucks, tire inflation pressure tables, light versus heavy loads, aftermarket tires, and such but apparently not as well as they need to.

By law, a dealer should not change the pressures even if they could. I am a little surprised that the settings are hidden out of everyone's sight (and touch), though. It wouldn't be the manufacturer's problem or liability if you modified the pressures yourself just like it is not their problem if you delete your emissions equipment.

 

[TexasCub]

Well hopefully someone will figure out the fix for this, I've been driving the truck since new with the light on. I'm used to it but would sure like to see it go away. It's not like the TPMS is doing me any good right now!

 

[Contisauto]

You would think that if you were to inflate your aftermarket tires to 80 psi that only take 65 psi because "the sicker and the EVIC says to" that it would be a liability on RAM because that 65 PSI tire could prematurely fail at 80. The lack of flexibility seems like a mistake and not well thought out. You can buy aftermarket tires all day long that only take 65 PSI and still have the same load rating. How stupid of RAM to lock this system up like that and/or eliminate the light/heavy load switch.

 

[TexasCub]

Absolutely, the dealer should be able to adjust the setting as needed, just like they were able to on the 2012's. Heavy load/Light load, it's really not well thought out.

 

[Jeff Gurr]

Getting ready to drop the wallet on some aftermarket wheels and tires. They don't hold 80 psi so of course my light will be on. Has anyone ever simply removed the bulb in the instrument panel? I'm asking in case there is a booby trap or some other failure that happens because of a missing bulb.

And if I successfully remove the bulb, what happens if I leave the TPMS sensors out of my wheels and completely off the vehicle? Seems like then it would be a moot conversation?

Worst case, I put a black piece of electricians tape over the light.

Thanks,
Jeff

If you leave them out you will get a service tire pressure system msg on the evic

Is that the same thing as is happening now while my rears are down from 80 to 60 psi?

 

[josephc1]

I hate the TPMS on my 2014 2500. I run 60PSI front and 45 PSI rear when empty witch is most of the time. When towing my 5er I up the rear to 60PSI, plenty for the 1800# pin weight ready to travel. I verified weights at cat scales.

 

[wyosteve]

On my 2015 3500 SRW, when I put my set of winter wheels/tires on which don't have pressure sensors, the 'service tire pressure' note appears in the EVIC when the key is first turned on, but as soon as the truck starts, the EVIC warning disappears. No other warning 'noises'!

Just to let you guys know it is very possible to change you tpms lower threshold. Dealers don't have the ability anymore (feds took it away) you have to find someone with an autel and acquire a 4 digit pin from your dealer that's tied to your vin. Cummins forum has a list of people around the state's that have these and will help you. Good luck.

Up yours feds lol

Yep, Zedman is correct. Had mine done a few weeks ago. I run the front at 60psi and the rears at 45psi when not towing the 5r. No light, no ding and no evic message "inflate to 80PSI".
