I have aftermarket wheels and tires. I want to run my tire pressures at 55psi. Can the dealer reprogram for that?

On 2018 and earlier models it should be possible but not likely!  On my 2014, I had the Dealer swap out wheels and tires from another 2014, before purchase, with an agreement that they would adjust the speedometer for the tire size difference.  It took the Dealer almost a month to convince GM to allow the correction and that was for a tire size that was already in their system!  I realize you only want a pressure change, but this should give you an idea of the resistance you may get.  I would just talk to your service department and see what they can do.  Just be prepared to elevate the issue to higher management.

Did you have to argue with them? I just called the dealer and they said no. But I didn’t talk to my normal guy either he hooks me up.

Well.... No..... But I had my daughter get it done as she was working there as a service advisor at the time.

I was pretty certain they could do it. But not if they would.

It can be done via a reprogram of the BCM I think?  Last I recall.  When they do the BCM setup it asks for TPM pressure specs, which are entered via what's on the tire load door tag.  

 

What pressures are on your door label?  On my 2015 HD, the rears were tagged at 72psi.  I was able to get to 56 or 57psi when the light tripped.  I ran 60psi all 4 corners never had the light come on.

My door says 60 front and 80 rear. I tried running them at 60 and the light still comes on. At 62 it’s fine until the temp drops at night.

Yes, the dealers have the ability to change the TPMS thresholds.  But, it is difficult if not impossible to find one that will do it due to liability concerns.  I tried and couldn't find one to change it.

 

I ended up buying a Mongoose Pro interface and a subscription to the GM programming software and did it myself.  Very easy to do.  The TPMS thresholds are in the BCM module.

 

With the GM software, I have full functionality to program and update all modules in the truck.  Interesting though that GM recently added a restriction for the number of times the modules can be re-programmed using the subscription for a specific VIN. I think this is so GM can determine if performance tunes have been dropped in.  I think the ECM retains something like 20 or 30 of the last programs dropped in it, so you would have to reflash that many times to clear the performance tune.  So, this is GM's way of cracking down I suppose.

None of the dealers in my area are wiling to do it, kind of ticks me off that they can, and won't. Liability because people are to stupid to check their air pressure, crap, even look at their tires....

I know exactly what you mean. I paid $200 extra for the sensors only to have my light on still because I don’t want to run the rear psi so high. My max towing weight is about 5k and that’s not very often.

I don’t remember where I saw it, but someone makes a tire pressure monitor tricker thing.  It’s a small device that stays in glove box or under seat.... and you learn the tire pressure monitor to it and the tire pressure monitor reads it instead of the tire pressure sensors.  No more ligh but you loose actual tire monitoring, so pretend it’s the old days.

Warning for pressures seem odd to me. I was not towing so I lowed the psi to 55 all the way around then weather temps went colder so psi reduced. Warning at 53 but not 54....then next time I shut truck off warning at 55 and 56?   So when I was back home I filled them up to about 65 before they turned green. Now I have front at 55 and rear at 60 when not towing (70 rear when towing).

Find an independent shop to do it, any shops with modern equipment can do it. A friend owns a shop and did my 2015. We had new tires put on a 2015 truck at work at another independent repair shop and had them reprogram the tpms also.

I run 50 psi all around when empty, so I have to clear the warning every time. It definitely gets annoying after a while. My dealer was able to reprogram my 2012 truck, but wouldn't do it on my new one.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.
