Tire size question.

[Merc Dr.]

I just put slightly larger than stock winter tires on my Pontiac G8 GT. I'm getting error codes for traction control and brake problems. After doing alittle research I found it's due to the larger tires. Will this programmer take care of this issue, or will it only calibrate the speedo? I haven't bought the tuner yet and want to be sure.

its only going to calibrate the speedo, as to whether that will make the car happy I am not sure.
