TPMS and Traction Cotrol
Vossen Wheel Model VVS077

Rear Wheels: 20X11 Offset +65MM Tires: 305/25/20




JMHO, but next thing I'd do is lower the car!!

I assume you got the correct sensors for you model year. The 2005-2009 C6 uses one model sensor, and the 2010 and newer uses a different one.
I don't know why your tire shop didn't program the sensors to the car when they put on your tires - unless you got the wheels/tires/sensors shipped already all mounted up and just installed them on the car yourself.
How are your sensors mounted in your new wheels????

Are the valve stems sticking out of the rims (in the OE manner), or are the sensors mounted deep inside the wheel with bands or brackets?

If they're mounted deep inside, you need to know EXACTLY where they are so you can get the antenna of the TPMS tool as close as possible to be able to trigger the sensor during the relearn procedure.
Now, to answer your original question.....without the sensors being programmed into the TPMS you will be able to turn off TC, but you will not be able to go into Comp mode or turn AH off completely. As soon as you do the relearn procedure to program the sensors into the TPMS, you'll then be able go into Comp or turn off AH all the way.
So....just get your sensors programmed and you'll be able to do whatever you want with the AH!!

I purchased the wheels and tires with TPMS already isntalled off of EBAY. The wheels were mildly used and were off a 2005-2009 C6. I assume the sensors installed were the correct type being they worked on previous vehicle.
TPMS were not programmed at shop (MAVIS Tire) because they didnt have the tool to program. (all they did was mount and balance). The TPMS is installed with the valve stems sticking out of the rims (in the OE manner).
You put my mind at ease re: the TC issue as now I definitely think it's related to the TPMS and hopefully when I get them programmed this weekend all will be back to normal.
Now about lowering...the car is so low already! I know it will reduce the gap between wheel and fender but worry about the constant scraping.....
Again thanks for the help!!!

EVERY car built since Sept 2007 (the beginning of the 2008 model year) has tire pressure sensors and a TPMS!!!! The C6 has them because starting back about then manufacturers had to start phasing them in, with 100% of their cars having them by Sept 2007.
Any tire shop that doesn't have a TPMS tool is posing.
Anyway, take a look at the video below so that when you go to a real tire shop you can ease the process by knowing how to put the car into the learn mode. They'll have a guide so they can look it up, but if you know the procedure it will only take about a minute to get it done.
Good luck!!

also -- to put the C6 in learn mode for TPS setting and use the tigger tool --
-- put the vette in accessory mode ( ignition switch -yellow light )
-- on your FOB hold both the lock and unlock buttons until you hear the horn beep...
-- start with your front driver side wheel.. you have set it when the horn beeps again...
-- repeat process with front passanger , rear passenger and finally back rear driver.
== when you are done, the horn will sound multiple times.
DO NOT do the above unless you have a TPS trigger tool as XXX will be displayed on your dash until setting the TPS .

The little ATEQ VT-5 looks like a good TPMS tool. I've used several other ATEQ models and they are very good, but I haven't used the VT-5.
Here's a link for an even cheaper and more fully featured tool - a TIPS tool like I used in that video a couple posts back:
http://www.ntxtools.com/network-tool...-TIPS003A.html
The TIPS tool has some diagnostic capabilities the VT-5 just doesn't have, and it's a completely universal tool that will work with virtually all sensors out there that require a TPMS tool. I believe the VT-5 basically just works with GM sensors (and a few others) that only require a simple continuous wave transmission to trigger them.
Just as a reminder to any owners of a 2010 or newer C6, in 2010 a different TPMS computer was put into the C6, and it uses a different tire pressure sensor from the 2005-2009 C6.
The 2010+ sensors don't require a TPMS tool to trigger them - you can do it by changing air pressure in the tire. A tool can be used as well, and that would be a lot quicker and easier than messing with your tire pressures if you swap wheels frequently.

Wish I had known about the tool on tirerack as I paid a bit more for mine.
C6 OE
rear tire = 26.8"
front tire = 25.7"
your tires
rear tire = 26.0"
front tire = 25.5"
