You need to have the computer reprogrammed for the tire change.
I think the dealer can do it.
Or you can get the Hypertech or Powerloader, etc.

Re: wheel size effects traction control switch!? (jpvette1)
I just put on GS rims 17 x 11 and BFG 315/35/17s and have the exact same problem and now don't feel as bad. Really no big deal as I don't drive the car in the rain anyways but when it first happened on the highway sunday I thought I blew my tranny b/c I wasan't going anywhere when giving major gas (no realizing yet what was happening). I tested a little bit in competive mode and so far so good but the verdict is still out. I have no clue how to fix this problem but I can think of worse problems :D>

As long as your rear tires have a larger diameter than the fronts the TC will not activate. I run the GS rims when I am on the track and have often driven on the street with them. With 275/40s in the front and 315/35s in the rear I have never had the TC activate unless I was spinning the tires. One time as an experiment I put the stock 18 inch wheels in the front with the 17 x 11s in the rear and the TC came on right away. In fact it applied the rear brakes while the car was coasting down hill in nuetral.

I have 275/40 Nitto DR's on 17x8.5 on the back for racing. I have been leaving them on and I have never seen this message. Also I have no sensors in the rears and, not only am I not getting a tire pressure message on the DIC but I also have pressure readings on the DIC for the rear. I even disconnected the battery for 2 days and still getting DIC rear tire pressure, but I have no sensors.

I have the same problem but not as bad. The TC is very picky now and activates without wheel spin. One time is was coasting and it kicked on as well.
Now its just habit to turn it off.
