Where is a good source to get decent TPMS? Im assuming there are some that are better than others. Ive got a set of AEV Savegre's coming that Im going to be getting installed and am going to be selling my Rubicon takeoffs with the TPMS and I dont want to break them apart to get them.

Currently they are stored about 8ft from where I park every night. Maybe that's what it is? Seems like if you had low tire pressure you should be alerted more quickly though.

If this is true I could leave home with low pressure and take a road trip travelling hundreds of miles on a low tire in one day before being alerted. Kind of defeats the whole purpose of the TPMS if they are not updating more real time than once a day.

Mine TPMS would come on as soon as I air down and turn off as soon as I get off the trail and air up. I got rid of the TPMS with the take off set that I sold and got a procal because it can recalibrate down to zero.

The car I had was a Toy Camry, I was able to drive away from home no sensors and no light, the previos post says it comes up as soon as he lowers the pressure, thats good!

I dont care much for sensors, I check the pressure often

Just remember that the sensor reads the spare and the 4 wheels on the JK.

Do sensors vary from year to year? If I get Rubi take off's from a 2011 and put them on a 2008, will it matter? (Thinking not, just want to be sure).

Has anyone done this? I now have 2011 wheels/tires but noticed the valve stems are all black (my '08 are gray). Think my computer will recognize these 'new' tpms sensors? Would love to hear from someone that has already done this same scenario... 2008 or 2009 Jeep with 2011 Rubi take-offs.

Mine took 3 days to come on of driving to work and back. Now I cant wait to get rid of it

And what did you install? Take offs or new wheels w/o TPMS?

A lot of info flying in this thread. Some good, some not.

JK TPMS sensors have a grey aluminum stem normally with a grey cap. The stem is aluminum, the cap is plastic. The stem is threaded and the outer nut holds it rigidly on the rim. If the stem is black rubber you do not have TPMS sensors installed.

Part numbers: Sensor 28155. Stem 20020. Rebuild Kit 20013.

Anytime a tire shop breaks the bead on a tire they are supposed to service the TPMS sensor. They are supposed to use the 20013 above which costs about $6/tire. The kit is an O-Ring, Nut, Shrader Core and Gray Valve Cap.

Up to and including '09 all JKs used the same or interchangeable sensors. Not sure what happened after '09. Domestic JKs are at 315 MHz. Export JKs are 415 MHz.

The dash light can take over a week to light when a sensor goes missing.

When airing down for a run or airing up after a run, yes, the TPMS will immediately light the dash light or extiguish it. It does this quickly yet does not detect a missing sensor for a week or more.

The JK does not learn new sensors. The sensor IDs are flashed to the computer. A good tire shop or any dealer has to change the IDs.

If your original tires are stacked in the garage they are not reporting a pressure to the WCM. After sitting still for 20 minutes the sensors shut down and stop reporting. When the JK moves again (tires start turning) the sensors start reporting pressure and continue reporting pressure once a minute until they are stationary for 20 minutes. After sitting still for 20 minutes...repeat.

If your original tires and sensors are stacked up and you want the TPMS sensors in your new wheels, you can do it yourself. You will need all of the factory tire changing equipment, a 8" long piece of 2x4 lumber and a willingness to rotate your tires. If you do not want to rotate your tires you will need a jackstand.
