I purchased 4 TPMS sensors on ebay for about 35 bucks, my tire guy didn't charge to put them in my Solstice rims...and it takes all of 1 minute to reprogram your own sensors...at least on my 2008.

Details are in the owners manual.

 

Just called the dealer & he said the sensors go for $75 a piece!

 

According to this, yes.https://www.chevyhhr.net/forums/tires-wheels-49/tire-pressure-monitoring-faqs-20882/.

 

The procedure for resetting the position is really quite simple, it's in the owner's manual, and here several places https://www.chevyhhr.net/forums/showthread.php?t=20882
I did not really mean busting your own tires down, but theoretically a tire store is capable of the operation. I have assumed you meant to have your winter tires mounted on rims in your garage during the good/off season. If you mean having them remounted every year, then you just re-learn or make sure they go back to whence they came. To be clear the TPMS sending unit is attached to the valve stem inside the mounted tire, not to the tire or directly to the rim. Did that help, my wife says I confuse people.
If you live in a state that requires safety inspection, the TPMS light will be cause for rejection.

 

I just found sensors under ChevroletTireSensors.com for $31.30 each, can I use these on my winter tires instead of the dealer ones at $75 each?

 

Yes.
I got mine from a discount tire retailer for $30/ea.
Thet are the "orange" sensors/ Must be an internal code they use.

 

Can most any tire place put everything together; rims, tires, and sensors? Then do the wheels have to go to the dealer to be "trained" or can I teach them myself using the owner's manual? (I work with horses and find mechanical things confusing.)

 

Yes they can assemble everything, and you can reprogram them yourself, or you can negotiate them doing it. They have a thingamabob that does it quickly. But, if you buy everything somewhere else and ask them to do it.....

 

to do it yourself involves with a procedure of tapping your brakes etc to put it into learning mode, it blinks a blinker which tire it wants and you let the air out for like 8 seconds, and it honks at you, repeat. It is easy.

But them walking around the car with a computer for 10 seconds is easier.

 

I had a problem with this situation. My monitors were not being read by the main sensor. I took it to the dealer as a warranty repair. They charged me $50 to reset the sensors with their "wand". I complained that I should be able to reset the sensors on my own, in my driveway, and that is the feature that is not working. I got nowhere with them.
