Quick chargers? Wow, must be nice! We don't have any such here in northern Canada. As for putting just winter tires on the front of the car, very bad and dangerous. I have 4 WINTER tires on my Leafie. With the weight of the car, it feels like a little 4X4 Jeep. In winter here I get about, in your miles, approximately 80 miles range on a 100% charge.
I recently drove it back from Montana to home, 200 miles and had to stop 3 times, 2 for 100% and 1 charge at 60%. In the vast open spaces, there is nothing and for 10 miles I was driving on zero battery, even turned off my headlights (NO one was out) to save some power. Made it to the charging station and glad it was operational. Slept in the car with the heater on for 4 hours, bring blankets and a pillow. And made it home exactly 1 hour before a huge storm hit with sub zero temperatures and snow, in fact it got so cold, so fast, that a thick fog descended upon us due to the temperature differential. It ended up at -32 degrees, but by then the Leafie was snug in her garage and plugged in to 80%.
