I asked that question at my dealership and was told no. It would be nice if software could be updated when tire sizes are changed.
Unfortunately, there is no adjusting the speedometer or at least, not until or unless an aftermarket company comes out with a programmer to do it.
Hey, My dealer explained that the real speed is allways a few km/u less than what you see on the speed indicator. If you drive 50 km/u, it is in real time around 47 km/u. So, you can put bigger tires on to reach the same speed as it shows.
