Tire pressure monitor defeat with aftermarket wheels

Does anyone know if you can defeat the tire pressure monitor alarm after installing different wheels?

i haven't had to deel with jeeps tpm system yet. but on most new vehicles, changing wheels will cause the monitor to show a problem all the time. i hate tpms, and they have had so many problems most people ignore them now. they were mandatory on every new car from 07 on, and were on lots of cars before that. one more reason i hate new stuff. but it most likely has a sensor as part of the valve stem, so it needs to be transferred to the new wheels and should be able to function correctly, as best as that can be

right now im pretty sure nobodys found a way yet but itsjust the valve stem so you might be able to put the stock stems in your aftermarket rims. i know people have tried to put them in a pressurized tube(like ou can with audi) but i guess thejeep ones need to see movement or they trigger the light

I am not sure if the stock TPMS can be used in an aftermarket rim due to the fact that the TPMS itself having quite a bit of weight. I know that the stock wheels from Jeep should have a counterweight built into the wheel itself to offset the TPMS weight.

id guess you would justneed more balancing weight. a stick on weight opposite of the valve would prob work.

Get the AEV Procal, you can set the psi down or disable the TPMS all together.

Seeing as of 08 all cars sold in the US have to have TPMS, I'm sure aftermarket wheels can be used or there would have been a lot more press about this.

As far as defeating it. how about getting a 6 inch long, 4 inch diameter piece of PVC, and two endcaps.. drill 5 holes, mount all 5 sensors, glue on the end caps and after it dries, inflate to 35psi and cable tie it somewhere in the engine compartment out of the way. make sure it is accessible in case it leaks so you can pump it back up.

the pipe method wont work, the sensors need to see rotation or they make the light go on.

aev procal sound like the best way. good thing i have a 07 and dont have to worry about it

In some cars that may be true, especially the ones that don't actually use sensors but measure the rotation differential through the ABS system, but I don't think so on a Jeep as the TPMS system keeps track of the pressure in the spare and it is not spinning. I have had my alarm come on when the spare got low. And it goes back off when I pump it up.

What the heck is up with that? Your spare on a relatively new JK has lost enough pressure to trip the sensor? The only time I lost any significant pressure in my spare was when I was hit from behind and my spare tore a new one out of the hood of the toyota that hit me?

I think they only had about 32psi to start with and when it got colder this winter it dropped below the limit. I had checked the other 4 but hadn't bothered with the spare.

There is a receiver unit in each wheel well so putting all the sensors into one pressurized tube would not work. Also, I believe that they need to be spinning to send an electric current as they are powered by inductance I think.

If that was true you wouldn't get an alarm when the spare went low.

Does it show an alarm when the spare is low? I am assuming that you mean it is not being used but just mounted the rear still, correct?

When I first got the JK the tires were a little low for my taste so I pumped the four on the road up., but they did not set off the TPMS.

When we got to cooler weather, the TPMS went off and it drove me crazy until I checked the spare.

A few months later I got a flat, put the spare on, and the light did not go off until I got a new spare and put it back on the rear of the Jeep.

So from this I infer, (meaning I have no actual technical knowledge of the exact workings) that all 5 sensors work the same, and do not need to be rotating to send the occasional signal to the system.
