TPMS on my 2018 2500

[carden260]

So I have a 2018 2500 and the TPMS warning lights are driving me crazy. I don't need to run my tires with 80psi to drive around with. I was thinking of removing them from wheels and building a container that i can put them in a pressurize it to 75psi and throw it under the seat or in the bed. I know its an RF signal but does the ECU need to see them in motion or not. I don't want to go thru the hassle of dismounting tires and removing them if its not going to work.

Thanks

If it's like our previous years, the sensors must be in motion to communicate. search "how to set TPMS to any pressure" and you'll find the gurus you seek. The Autel scanners can be used to adjust the settings.

The AEV Pro Cal module can also be used to lower the TPMS threshold.

Not on the 2018 totally different system. they changed everything on it. thats why Iam here asking

i have a 2016 2500

- asked the same question about a sealed container to my buddy who owns 3 dealerships
- he, asked several techs at his dealers.
the sealed container trick will not work anymore, as it did many years ago. the sensors are too smart and need to rotate to activate and communicate. gobernment in our trucks stinks. cheers!

Just another reason to purchase a 3500 vs a 2500! SnoKing

I've run with 80 psi since new. No issues.

If you want, take one front tire off and put it in the truck bed. Run with your spare and see what the computer reads. That will give you an idea if the pressure can will work. Let us know. I have been running my 2017 at 35psi for 5,000 miles and just ignoring the light. There are some many other light on I dont even notice it. Yellow or green Exh brake, trailer tow, auto lights on, high beam whats one more?

When I run empty at 80 the truck tells me about every ripple in the pavement.

 

[kthaxton]

Yeah, I sure don't like the ride with 80 psi!

 

[m37]

I agree, and my truck has the air ride rear suspension which still doesn't make up for 80 psi in the tires.

Not the cheapest route but some tuners let you shut it off, Edge?
My 2011 2500 has a high and low load setting which was nice when I had it turned on.

Some reason why?? I run 65 front 50 back, unless towing then 65 front, and 80 back.

I know what 80 in back feels like empty see no reason to get beat up, maybe the 2500 is more gentle with 80 psi.

Nope, the only reason I hear is that it was mandated by the government for reasons of highway tire failures due to under-inflation. You only need to run 80 psi when you are at max GVW, weather towing a trailer or just hauling a load. Tire pressure keeps the sidewalls from flexing. Flexing the sidewalls requires weight enough to overcome the "pounds per square inch", if you looked at a graph, it would be like a sliding scale, less weight requires less PSI to do the same thing (keep sidewalls from excessive flexing). The people that make you keep 80 psi in your empty pickup truck tires are same that can't figure out how to control the speeds on a train.

My Dually has the air ride. When leaving the Dealer I was like holy crap this thing rides rough. Got home and YUP rears were 80. Lower the rears to 35 solo and MUCH better ride.

I am here to tell you that it is not....

Hard to imagine its not.

What I find hard to believe is that my air ride truck needs the tire PSI lowered to <40

That's what the door sticker says and I really never thought more about it. I've run that way for nearly 4 years. With the progressive coil springs, I fine the ride just fine. It can be a little rougher when the road has big tar strips but I can usually run in the fast lane which is always much smoother. Maybe I should let some air out and see what you guys are talking about.
