Speedo reprograming

Does anyone know if you can reprogram the computer / speedometer to compensate for a tire size change?

Thanks in advance

This might sound simple, look in the manual. If it is not there, try your favorite search engine.

I have heard of it being done, not sure you can do it.

Now if you had a ScanGauge, there is a setting for that.

...for GM products, there's an after-market "box" that can be connected in-line with the wheel Speed Sensor that allows you to 're-calibrate' the number of pulses per mile being sent to the ECU.

...unfortunately, I don't know of anything similar for a Kia.
