TPMS sensors on winters
My apologies if this has been covered in other threads, despite my searching.

I have a 2012 Limited. I have an appointment in a few days with a local shop to install new wheels and winter tires. I am trying to avoid installing TPMS sensors due to the high cost. (I promise everyone that I will be very diligent to manually maintain tire pressures.)

What will happen if I do not install TPMS sensors? One Jeep service advisor stated that there is a chance that the warning will go out after a while, that he had seen this happen on some recent Chrysler 2012 products. Other service advisors state that this warning light will never go out.

Assuming the warning remains on all winter, what kind of a warning will I see? Is the warning overly intrusive or relatively subtle? Can I still scroll through all other parts of the EVIC?

Thank you.

You will get a smaller amber light in the dash panel, same one you see during lamp check. After you start it will flash for 75 seconds and go solid. In addition, every time you start the engine you will get a warning displayed in the EVIC and perhaps a single tone. You will have to press one of the buttons to clear it, but otherwise the EVIC display is the same.

A set of four new OEM TPMS sensor have been available on ebay for like $75. Thats what I put into my winter tire set. Search for part number 56029398AB to get OEMs. Folks used to have problems with non OEM sensors, dunno the current status.

Edit: Looks like about $50 for an entire set now. Tire shop will probably charge ~ $10 each to install the sensors when you have the tires mounted. So thats less than $100. I'm thinking $100 is not "high" cost, but you may have a different opinion.

Re: TPMS sensors on winters
Thank you ColdCase for your detailed reply on this. The dealerships here in Canada charge in the $75 range for each sensor. I am amazed that the sensors are so inexpensive online. I do agree that buying them online is not a lot of money.

Since I posted this email, I got in touch with my friend whom owns a Jeep dealership where I purchased my Jeep. His response to my question about the need for TPMS sensors is as follows: "the light will eventually shut off as the vehicle will go into what they call a winter mode. You will not have any warning at all if you don't purchase the sensors and nothing else will be effected. Personally , i would not spend the money for the sensors. If things don't go as advertised let me know , but the warning lights should shut off without the sensors. "

Again, thank you for your help. I will give the no TPMS a try. I do agree that buying online is relatively inexpensive.

I'd be interested in finding out just how long eventually is. I had a warning that lasted for over a month of daily driving before I had the sensor repaired.

I'm not sure how widely its known that sensors can be found for less money than the $70-$100 tire dealers typically charge.

Re: TPMS sensors on winters
When we put new rims and tires on my Wife's 2012 Overland the TPMS sensors we got were for the 2010 and older WKs. They were installed by mistake and didn't read right. The tire shop shut them off with their scan tool (or whatever it is) and we haven't had a dash light ever come on. Ill have the proper ones installed on the next tire rotation. Others have said you can't turn the warning light off but ours has been off since the tire install in May. They did it with their hand held scan tool, nothing done under hood.
