I've been quite happy with my 2020 120Ah i3 BEV, but recently I've too often ran into situations on relatively low highway speeds (around 80km/h -- 50mph) that rear loses grip even on most gentle acceleration or careful regen/braking I'm able to do. Road has had no visible ice, it is just slippery (-2C, no salt). The result is rear loosing grip, and desperate wiggling and squirming when ESP tries to restore stability. Other drivers seem to be just fine.
Tires are Continental VikingContact 7. I'd guess the set has been driven under 10000 km and that were likely manufactured in 2019. I thought these were supposed to be pretty much best possible winter tires available for i3.
I'm starting to seriously loose my confidence to the car. Now even slightly curving road makes me horrified in these near-zero (Celsius) degree conditions, as fear of suddenly loosing lateral grip is always there. I'm feeling like the safe speed limit for the car in winter is around 50 km/h. I'm happy to drive slow, but it is not exactly safe when everyone else is going 80-100 km/h...
Any thoughts, like is this normal i3 behavior? Could a 3-year old tire set be so significantly degraded? Could new Nokian R5 give significantly better grip? Is there any other options? Should I just change the car to something else?
