Does anything have to be done with the tire pressure monitor system if you include the spare in a tire rotation...The EVIC shows the pressure of the 4 tires, how does it know to now read the spare as a working tire...

It says in the manual that the tpsm Dosnt monitor the spare tire. Only the four on the jeep. I don't know how it works at all but just something I have read.

I believe they work off inertia... As long as the receiver see's 4 signals, its OK. The spare isn't spinning, so its basically dormant.

For the 2012 model, I have verified that this is true.

2013 has a different TPMS system.

The 2013 sensors are read by the computer. It only reads whats on the wheel base in motion. Each tire/wheel has a sensor including the spare. When the spare is mounted on the tailgate it is not being read. All the others are and will be regardless of which you use.

The ones moving are sending info to the computer.

So if you have the EVIC display, will it automatically know the location of all the sensors after the rotation ?? Or does the computer have to be told where each tire is for EVIC to be correct ?????

2013 is all automatic. Rotate and drive away. I usually check each tire myself to be sure they are all 35PSI. Dash display is never off by more than 1 PSI.

5 Tire rotation is recommended as you would wear all of them out, last longer and when you are ready for a new set, get a new set of 5 (gives you the option to go with a different tire if you choose)

I do a 5 tire rotation every 5000 miles along with my oil change.

Can you cite where you obtained that piece of information? I just bought a 2013 and swapped the tires and rims off my 2012. The TPMS isn't working. While that would seem to support your statement, I have read other posts (AEV Forum) that stated the 2013 did read older sensors. I tend to believe it doesn't. However, I would like some further info before I buy a whole new set of wheel sensors.

Plus 1 on the tire rotation advice. You could end up throwing a perfectly good tire away by letting it sit on the tailgate rotting away.

Oil change at 5,000? That's an ongoing discussion that will be debated into eternity!

I always rotate five. Like others have said waste of tire if it just sits on the tailgate. And if you need to put in four wheel drive all wheels have to be close in size or it cause damage to the diffs so I have been told.

I just did a 5 wheel rotation and I can't get the computer to recognize the front driver side tire pressure. I have driven about 300 miles so it has has plenty of time to sync up. The tire that's out isn't the one that was the spare. I'm thinking i may have to have them reset at discount tire. Any ideas? Below is the way I rotated them.

I am just too lazy to do it more frequent than that. Plus, I am a bit OCD, multiples of 5 are a tad bit easier to remember at first glance (I know, this doesn't make sense....call me crazy:))

Makes perfect Sunny, I'm the same way. Both of my Jeeps are on a 5k schedule for oil and tire rotations. :thumb:

My tires have always gotten loud after rotating...do you experience this with the larger tire sizes as well? Or have I just had bad luck? I dont even rotate anymore :whistling:
