My other car is a 2017 Ford Cmax Energi. It came with Michelin Energy Saver A/S tires that would start squealing at the sight of an onramp.
When I placed lightweight Konig wheels and slightly wider Pirelli Pzero Nero GT tires on it, the driving characteristics completely changed (from eco-saver to super-fun).
I'm not willing to go down the route of custom wheels, and I will assume BMW has done us well with lightweight wheels. I have done some minimal Googling, and haven't found the answer to a related question: Do the rear i3s wheels fit on the front axle of an i3s (that is, clear the suspension and wheel well arch)? If yes, then would it be interesting to go square and then be able to fit the S001 performance tires all-around?
