Question TPMS metal or rubber stem

I'm trying to order replacements for my 12 year old tpms sensors. Can't believe they lasted this long. Rock auto is showing two possible parts, both ac delco. one has a rubber stem and the other is metal. What do you recommend? I actually lost a sensor when a tire shop roughly added air to my tires and broke the metal stem. Maybe a fluke.

ACDELCO TPMS171K metal

ACDELCO TPMS175K rubber

gmpartdirect has a rubber stem unit for about ten bucks a piece more. A tire dealer wanted 200 bucks to install them. That seems high .

You can purchase what you want at your local tire store and have them installed. It might cost you less to do that. Metal or rubber stem is totally up to you.

I believe there was an issue with the early metal stems rusting. Road salts?

They became easy to break.

But you can get that part #, and search on ebay, Amazon and see if someone has a set of 4.
I recall the older model replacements were a bit more expensive than the newer sensors.

I had a small tire shop install them when I was replacing my tires.
It was an additional charge of $5 per tire to pop them on.

I would personally go with rubber version/

Hogwash!!! The metal ones are aluminum alloy. Rust is not a problem. Heck, roads here get treated with a solution of salt and water from merely a mention of the word "snow" on the news. They'll crack, or break when some ignorant tech pulls the tire chuck off without regard to the type of part they're working on, though. My metal TPMS lasted nearly 10 years, through 2 sets of tires.

Ask another tire dealer about changing them for you. They only need to break the bead on the outside of the wheel to change a TPMS (either type). There is no need to rebalance the wheels when they do it that way, either, unless the tech screws up something.

Another dealer quoted me 500 bucks to replace the sensors with his non Delco units. Predicted only 3 years battery life. yikes.

I guess you're going to pay a hefty price for procrastination. It's beyond comprehension why you didn't think about changing the TPMS sensors as part of routine maintenance when you got a new set of tires (second set in my case).

Actually I tried getting sensors two years ago when I replaced my tired. The tire dealer wanted 90 bucks a sensor and 100 bucks labor. About 460 dollars. Thought that was a rip off and refused the offer.

That's pretty interesting. Was it the same tire dealer you went to a few years back (2014) when you broke a TPMS sensor stem and wrote this post to the forum?

Not the same dealer but I tried him also as I remembered how cheap he was. Not cheap any longer and said his sensors last only 5 years.
Wouldn't install ac delco because he didn't have the right calibration tool. (don't think you need it) i'm going to order the delco units since they have worked well on my tires.
