TPMS question
I'm thinking about upgrading my base '16 wheels to 19/20 Cray's. I'll have to buy new tpms units. Once installed how are the new units learned/recognized by the computer?
Thanks..

New TPMS sensors are recognized instantly. No programming is necessary. You don't have to do anything.
I just put a new set of all-season tires, new wheels, and new TPMS sensors on my car last week. I had them mounted and balanced, brought them home, and put them on the car myself in my garage. After I finished, I started the car, and instantly had pressure readings on all 4 corners.

My TPMS logs in a new set of tire pressure sensors automatically.
But mine don't do it instantly!!
I run a few psi less in my track tires than my streets, and when I swap from street to track wheels/tires or back the pressure from the set I just took off stays displayed when I first start up after switching.
I believe you need to drive above about 20 mph for a couple of minutes for the new set of tire pressure sensors to "learn" themselves into the TPMS.
After swapping on a different set, when I start to drive above 20 mph with the pressures displayed it takes a minute or two before the new/different pressures are displayed -and that's how I know the new set is now programmed into the TPMS memory.

Since my new tires were inflated to the same psi as the tires I took off, perhaps I was getting the old readings "instantly," but the GM sensors used in the C7 update every approximately 10 seconds when moving so one wouldn't really notice. I know that because I watch my pressures fluctuate that often when watching cold tires go to warm tires when starting out.
That's the point, it's "instant" and "trouble-free." Is it really all that important that it took you a couple of minutes, which is essentially "instant," to get the new tire pressure readings?
One of the issues on this forum is that new people often come here to get simple answers, and they usually get those, along w/ a bunch of "dissertations."

I always set the new wheels/tires to 35 psi so I will know that the TPMS is working on the new wheels. It takes about 10 minutes of driving before the 30ish settings move to 35ish. Later I drop the pressure to the 30-32 I run normally. I change out wheels/tires monthly so like to know the change was effective.

I did not have Discount Tire remove the original TPMS from the wheels as I sold the Z51 wheels and left the TPMS in for the new buyer. It made the sale much easier.
Be sure to order the correct TPMS model number for the Vette. Any TPMS will not work properly for the read/learn sequence.
Paid: $29.07 each

I have a question. I bought new wheels with sensors already in them but the sensors are reading on opposite sides. For example, the car thinks both right sensors are on the left. I did a reset through the gauge cluster with no change. What can I do except switching the sensors around?

Go to a dealer
buy the reset tool
live with it and remember.....
Id do #3....

My guess is there is a problem with the C7 reading/relearning the sensors on the wheels you bought. Take your C7 to a local tire dealer and have them read the sensors or do as "Glen e" suggested above.
There is a problem somewhere in the system.

When I bought my new ACDelco 13581560 GM Original Equipment Tire Pressure Sensor Sold by Amazon.com $29.07 each TPMS for my 2015 C7 there was no way to differentiate the sensors. There was no left or right, front or back.

As long as they are reading is the most important part.

I'm getting confused in this thread on whether the car is able to differentiate Left from Right during the learning process.
When I bought my second set of wheels, the guy used a tool to reprogram the new sensors to mimic the original ones. Sounds like that may not have been necessary based on a few of the posts here.
But I don't get how the car would know which signal is coming from which wheel during the learning process.

How do I know? I installed new TPMS on a new set of Z06 Reproduction wheels for my base C7 1LT this spring.
The correct TPMS is the ACDelco 13581560 GM Original Equipment Tire Pressure Sensor. I bought mine via Amazon for $29.07 each.
