Track wheels TPMS?
C8 will be my first Corvette, mainly used for fun on the track, though I plan to drive it there and back.
While it may be too soon to know for certain, what is the latest tire pressure monitoring tech GM uses on the cars? Have a set of wheels on the way, and would like the computers and things to still work ok, mainly for those to/from drives.
In the old days you had to get a set of TPMS sensors and pair them with the car. Anybody have an idea what it’ll take to keep the C8 from freaking out with aftermarket wheels? What’s the process for a ‘19 C7? Tire f/r ratio is being kept stock.
Thanks!

I once had a rt rear blow out during a pursuit when I was at well over 100 mph. I did some cool NASCAR spinning skid marks on the highway and luckily stayed on 4 wheels. I often thought if a TPMS alert would have allowed me to slow down before the tire disintegrated? I personally would like TPMS if I tracked a car. I'm sure the real racers will come on and give you the answer. I'm curious.

Yeah not looking to have TPMS save me on track - just want to be sure I can use aftermarket wheels and keep the computers out of failure/limp mode. Bonus points if there is some way to keep TPMS functional and eliminate dash error lights.
Anybody have a late C7 with aftermarket wheels and have this figured out?

I’m curious too as I know on my C6 you have to run either all 4 corners with programmed sensors or not as if mix matched it will not allow you to turn off stability control. I almost found that out the hard way having it try to straighten me out and almost putting me into the curb trail braking into a corner at ~90, thought the car was possessed at first then realized it hadn’t turned everything off like I thought.

I picked up a sheet metal screw in my rear 325/30/19 C6 GS tire. I believe the monitor came somewhere below 25 psi. It was a slow leak. I had a 12v air pump and added air. Found out the pressure sensor sends an alert for too much pressure as well. (Over 40 I think). Allowed me to get home at night the 150 mile stretch without riding on the “run flat” sidewall . I stopped every time the pressure got below 25 psi. I’m a big fan of TPMS. The C7 shows the tire pressure along with other data in Track mode continuously. Small pressure changes show up reflecting tire heat changes. Tire heat also show up. Valuable info even if I’m told the heat is approx. I’ve found my TPMS readings to be very accurate because I verified mine against a professional grade dial pressure gauge. I would assume most people do that.

Had this dilemma w/ my C7 Z51 that I setup for TimeTrials. Ended up adding TPMS to all my wheel sets. The C7 used the tire temp sensor data to feed the eDiff. If no data was present it would enter a default mode. Even Jim Mero wasn't 100% sure if it would default to a medium setting or max performance. On top of that, if you have a slow leak it's nice to know. A buddy who races a Mustang was notified of a puncture before heading down the back straight at Road Atlanta where he hits 150+.
Yes it's a little extra expense, but you ensure all systems work and with the C7 (assume the C8 is the same) the sensors auto-sync so you don't have to do anything other than swap your wheel set and drive a little.

As said, if you got the Z51 or if your C8 has the eLSD rear diff you will have to use TPMS sensors. The TPMS sensors on cars with the eLSD rear diff actually do 2 things, they provide PSI and temperature inside of the tire. It affect the calibration for the eLSD.
I would ask the wheel company which sensors their wheels are setup for, the GM ones that I have messed with use a long shank style nut on the outside of the wheel t secure the TPMS to the wheel. And contrary to the other posts responses, you do need to sync the TPMS sensors to their position on the car. If they are new sensors they also need to be paired to the vehicle and then sync'd to the position on the car. Once GM releases the sensor info that will help you determine what Mhz sensor to order and if the current TPMS reset devices on the market will work or not.

In the C7, could the owner perform the TPMS pairing? With my Vipers you had to take it to the dealer for them to do it with a special interface tool. Which meant the "Lo Tire" thing was on constantly with the track wheels.
Have both my selling and courtesy delivery dealers looking to see if they can get a spare set of TPMS sensors at delivery time.

TPMS data is integrated into PTM and all of the underlying systems. Given the minuscule expense, if you are planning on utilizing track wheels (i.e. my Forgelines were almost $5k) why would you even think about forgoing TPMS?
Looking forward to seeing your C8 @VIR soon! Not sure I will have my Z06 back in time for instruction with THSCC at the end of this month. If not, I'll be out in the Type-R.

I just learned there is a way to pair, or reset the TPMS by going to the tire pressure display while the car is running and hold the right side select button on the steering wheel for 5 seconds. The horn will beep and it'll reset the TPMS. I've been swapping between street and track wheels for 3 years and just recently, for the first time, the car didn't recognize them when I changed. The previous process fixed it though.
They are only like $35 on amazon and definitely worth it when running high speeds on non run flats.

That is not correct, you cant just install the wheels with the TPMS and drive. The sensors have to be paired to the vehicle and to each wheel position. The end user can do this as long as they have the TPMS reset tool depending on the frequency of the TPMS sensors.

Again, this does not re-learn or pair the TPMS sensors with each wheel position. All this does is puts the vehicle in TPMS re-learn mode. At that point you have to use a TPMS reset tool and go to each wheel position starting with the drivers side front wheel and excite the TPMS sensor using the reset tool. Then follow the side marker lights to the next wheel position until you are done.
