So much for TPMS auto-learn :-|
Yesterday was mid-30s in the morning, today was low-70's by mid-day... time to put the winter booties away and install some summer rubber. Just had the OEM Sport 4 S 's installed on some BC Forged rims two days ago, with Schrader TPMS sensors directly from a GM dealer (sent by the rim seller)... so I'll verify it's the correct sensors, but...
I drove around with the new rims/sensors on, expecting the car to eventually realize the old sensors weren't there... put close to 20 miles on it and it still shows the old values (it never threw an error screen saying to check the TPMS system). I thought the system was supposed to flag the missing sensors within ~5 miles, let it sit with engine off for 20 minutes, then drive for ~5 miles to relearn the new ones. But the car doesn't seem to achieve the Alzheimer's state. Guess I'll go out there and try to force a relearn, cross my fingers my C7 relearn tool is still good for the C8.

Yeah, I just tried the forced learn procedure... no dice.
Looking at the TPMS package my guy sent, it says 33560D... I can find that number associated with Chevy/GM, but not with the C8 specifically. I have a strong suspicion he sent me the wrong sensors, which is going to **** me off given how many times things went wrong getting them here in the first place (was supposed to be ordered with the rims, then ordered from his local Chevy place but they shipped to him instead of me, etc.).
Can anyone confirm/deny that 33560D is/is not for the C8, please?

Sounds like you got the wrong ones... Or, they may just need to be programmed as they appear to be universal aftermarket sensors based on that part # (are you sure they came from a dealer and not just a parts store?).

I requested the XL8 rpo code version, but he said they were out of the nuts for the metal stem version... he asked if rubber stem was okay, and I had no objection since some hardware gets swapped with each tire change regardless of stem style. What he sent was obviously not XL8, but it was Schrader (which is the OEM manufacturer) so figured I'd still be okay. If what you're saying is correct (generic version that requires programming), I'll have to take the car in and get the rubber dismounted/remounted just so they can get at the sensors. F me!
Have them (the wheel retailer) reimburse you sourcing your own correct pre-programmed ones AND have them schedule you a mobile TireRack service to perform the installation. At least this way it's entirely on their dime and saves you running back & forth to a tire shop.

Good luck getting this straightened out - does sound like you maybe received the wrong sensors for the car.

For other's future reference...
What I'm finding is the 33560 series is listed with a top speed of 115mph, so these would be no good for the track. The "proper" universal series would be the 33760, which is listed at 200mph. Programming is required, as expected, so I'll probably be looking for a good programming tool so I don't run into this issue again in the future (and maybe help out some locals in the process). I'm not sure if I can get away with programming these things while already installed (don't know the programmer antenna's directivity/sensitivity).
EDIT: I'm just going to bite the bullet and purchase the proper sensors... anyone suggest a good (inexpensive) source?

Oh, I should also add... driving into work this morning? Yeah, the car recognized the old sensors weren't there in less than half of a mile 
Some days... some days...
But good news, Kracka! My backordered red-flange pTR intake manifold, Eventuri CAI, and Lingenfelter 95mm throttle body are supposed to arrive today
Now maybe I can get that put together over the next few weeks and plop in my Soler controller.

I switch between track and street wheels a lot. Sometimes the TPMS recognizes the new wheels almost immediately. Other times it takes 25 - 30 miles. I bought my sensors from Wildhammer as factory GM parts.

Any thoughts on cloning? Pros/cons? It's suggested when you have multiple sets of wheels that are swapped out often (summer/winter, track, etc.), so two (or more) rims share the same code. Not sure how that might work with multiple sets of cloned rims within proximity to the car, though I imagine once all of the unmounted rim sensors go dormant it's not an issue.
Awaiting response from my local tech as to their schedule (and if I need to order sensors myself or if they have them in stock).
