2012 E350 cab TPMS in wheel or no?
We're getting ready to do new tires but not sure if the sensors are in the wheel or done elsewhere? 7 going on 8 years - should we replace all the sensors even though they are currently working? I know it's super expensive to just do one at a time later. Some time stores charge $100 just for one replacement. Of course it takes a special programming tool and pulling the tire off the rim (if the TPMS is inside) so there is no DIY.

Lexi,
Sensors are a part of the air valve and they do last 7-10 years or more I have seen. At some point if you are going to keep the car it may be wise to replace all of them at once while the tires are off etc.
Personally I had my tires purchased and installed by Costco and they do the valves as well and reprogram etc. I hope you are not going to a dealer, they will charge you a fortune..
Cheers

Thanks for confirming they are part of the air valve in the rim for this car. We would never go to a dealer for anything unless it's exclusively only available via them.
I recently went through the same thing with my Lexus SUV and it was a nightmare trying to special order tires and do them through Sams Club - it took several attempts - their programming tool was broken with no hope of fixing/replacing -ordered tires again and went to another Sams and they had no sensors with no hope of getting more - finally ended up ordering tires from Walmart - where they actually had sensors and the tool - it also ultimately saved money as the sensors were $29 each vs $45 at Sams - and the tires were also $12 less (each).
One thing I discovered is all these places advertise a price for a TPMS Service pack. Not what it implies - it does NOT buy you a set of new sensors.

Wait until you need tires or one of the sensors takes a dump. Got my Michelin Pilot Sport S4s from my local Wheel Works and they replace one sensor at a very reasonable cost. They are also very careful dismounting/mounting tires on our vehicles.
A Bridgestone tire on our Forester developed a sidewall bubble and they replaced it under warranty "no charge". Its good to establish a relationship with a local business.

This is not always the case that they are full TPMS sensors in the wheels. If you are getting individual tyre pressure readings then they are. If you have the system where you just get a low pressure warning across the system and can reset the baseline as a whole then they are not TPMS. In this case they use the ABS sensors to measure tyre rotations and work out from there if there is a change in tyre pressure.
Mine on a 2013 car for example is the latter system and I can just change valves in the normal way when changing tyres.
