I had aftermarket rims and winter tires installed from the get-go. Yesterday I changed to the stock (aerodynamic) rims with Michelin Pilot Sports. I reset the trip info and have posted the photo for your reference.

Some info about the driving: my commute to work is 127km one way, mostly highway. I set the cruise at 110km/h and don't drive the car any differently than I did my ICE cars (ie regular acceleration, no hypermiling). I estimate that of the 29000+ km on the odometer, about 85% is highway driving. This winter my commute times were about 82 minutes each way, consuming roughly 35% battery per trip on average. Worst was over 40% consumption when the temperature was below -30*C; 3.8km/kwh. Best was 30% with a tailwind; approx 5.4km/kwh. My average over the 29000 km was 5.1km/kwh on winter tires.

Today's drive in on the new PS tires averaged 5.8km/kwh, which is a nice little improvement and the best average I've seen since owning the car.

Hope this helps some folks wondering about efficiency on winter tires.
 
Purchased May 2022. Most of my driving is highway too but speed is usually 80 to100km/h. Just about to hit 29,000 We don't get quite as cold as you and no snow, no winter tyres needed. Average is around 6.7km/kwh. I hate the kwh/100kms so I set my display to the same as yours.

Glad I'm not the only one who thinks khw/100km is incomprehensible.

I like the kWh/ 100 km since it's similar to the ICE car I had which showed litres/ 100 k. I can then easily figure out gasoline cost per 100 km vs electricity cost per km. In winter I typically do 18 or even more kWh/ 100 km.
