I'm sure that's with-in the range of our finely calibrated and finicky ECU. Many forum members are running that set up in summer, me included. Without noticeable difference coming from the Traction control.
I can't say more since I don't have evidence to back it up, my opinion is that the TC works independent from the tire size, better question is would there be more wheel spin with the new set up. if the wheel spins under stress, TC will start doing its thing.
