Most after-market wheels are TPMS compatible, but not actually "usable" even in the mildest off-road scenario's due to there easily breakable stems.

One option I discovered during my research was using the banding method. This method is often used on aftermarket wheels that are not TPMS compatible
due to low profile tires ect.
After market bands are sold that incorporate bendable tabs for the insertion of the tpms valve stem. This seems really janky, but remember that the valve stem
on many tpms acts as the antenna. I've never seen it done, but by choosing an internal antenna sensor for this application in theory would work better.
You could eliminate the valve stem portion and attach the sensor using a small ny-lok nut and screw. I think this would also cut down on the counter balance weights
needed for balancing.

This method could be adopted by 4x4 enthusiasts who dont want to chance a long valve stem being sheared off by rocks or rough terrain. This would allow the user to
retain the TPM sensors and choose the valve stem of there liking (usually a short rubber or stubby steel stem)

FYI, I have a new set of the bands that you can have if you pay shipping. I went with rubber valve stemmed AC Delco sensors on my 26” billets and all is well so I don’t need the bands.

Thank you Mark! Doing my absolute best in trying to get rid of the system all together but if I dont succeed Ill take you up on that offer!
I need to disable both my AFM & TPMS, been talking to SuperChips via email and they keep saying there products do not disable TPMS although people who have bought it says it does..
The instruction even say it does, but also say that features are dependent on vehicle model....Im going to buy the FlashCal either way because its the same cost as the Range device and it does so much more. Cant get but "two line" replies back from SC, and that alone is enough not to buy a product but Im desperate.

Went to my local Tire shop and they were kind enough to give me a handful of used TPMS. Ive been cutting them open and its obvious the technology has grown leaps and bounds. Turns out all of them have a motion sensor/G sensor on them that puts them to sleep to conserve battery.
All of them so far are completely IC orientated, meaning that there is no way of just shorting out a motion sensor or adding a resistor to the barometric pressure sensor to fool the receiver. Also been reading some of the patents online. Some of these sensors need to have a certain value G-reading for a preset amount of time before they even turn on. In other words they need to be turning a 15mph for 5 minutes before they send a data packet.
Its become evident that the way to defeat this system is not through the sensor!
Tuning them out seems to be they way to go, setting the PSI values to "0" .
Now,..its just a matter of finding out which tuners are capable of doing so...

I’ve heard that nothing in the US is capable due to TPMS being a federally mandated safety feature. Only tuners sold overseas for those markets are, and if you import those back to the US they won’t work on our vehicles. If a company sold a product that could defeat US systems , they could be sued by the NHTSA. All computer controlled systems nowadays know their location and act accordingly. Good luck, but I too looked into this extensively and ran into nothing but dead ends.

I'm with Mark.

The ones I read about being able to turn theirs off were Jeep owners- maybe because they could be used exclusively off-road (on a farm, private land, etc.)? I think what they do is contact Superchips directly and they sign a waiver (or click an "I ACCEPT" box) and SC sends them an update for their tuner that allows this function.

I wrote SuperChips...


ME:
"Hello, can you please tell me if the "GM Flashcal For Trucks - 2545" Is capable of turning off my TPMS and AFM?
2007 Chevy Tahoe 5.3
If not, which products do you offer that can do this for my vehicle?"

THEM:
"The Flashcal is mainly meant to adjust tires & gears for Speedometer Correction.
You can see the devices for your truck here - https://superchips.com/shop/v/chevrolet/tahoe/2007/5-3l/
You would need a Flashpaq to be able to turn off AFM and add tuning.
We do not have a device for TPMS on that vehicle."


I tried again...

ME:
"Will the F5 GM Flashpaq - 2845 allow me to turn off my TPMS?
2007 Chevy Tahoe 5.3 Flexfuel"

THEM:
"No it will not"

Some options to consider:
https://www.instructables.com/id/Tire-Pressure-Sensor-Bypass/
https://www.amazon.com/s?k=2-Pack+B...00C,+TM66+and+A1A)&i=prime-day&ref=nb_sb_noss
https://www.tpmsbypass.com/product/ford-tpms-tire-pressure-monitoring-system-sensor-bypass-2-2/ (might work in GM products on anything 315Mhz (?)
http://www.tpmsdelete.com/ - This one is probably the best solution for what you are looking for. Youtube video on it is here:

Hope this helps!

Ok...the first one is the tpms sensors in a pvc tube trick, which sucks and apparently doesn’t work on most of the newer systems because they require to be spun for a certain amount of time. The second link is for an add-on tpms system, not a delete. The third is for Ford only. (Thanks for making me say Ford dammit) But the fourth is the only one I have found that has promise although it requires a dedicated USB port. I haven’t heard of anyone successfully using it but I believe the OP is going to order one. @Jolly Roger are you going to be the guinea pig? I’m curious if it works.

Ill be the guinea!

Yes, the TPMS Delete box is what I plan on getting if the SuperChips Flashcal does not have a TPMS delete function.
I have an extra switched (key on) relay set aside for just such a thing. Ill Velcro the box somewhere under the dash and hard wire the usb to something like this...

This way it will come on automatically when I drive, and still be accessible when I need to reset it in the event of a battery disconnect.
