Kona Elektro, 2021, 64kWh, 204PS During the summer holidays 215/55/17 I was shown a driven distance of 86km in the speedometer and the BlueLink app on arrival. After changing to the winter bikes 215/50/17 I was shown 91km. Original summer tyres and from Hyundai the suitable complete wheel set with winter tyres. Tyre pressure sensors were automatically detected after the wheel change. Yes, tyre circumference is slightly different (-3.2%). But a km difference of 7%? In previous cars I also had different tyre dimensions, but I never noticed that clearly. Do you still have to enter the other tyre dimensions somewhere in the computer?
