Around 2mm of tread is nearing the minimum 1.6mm limit, so you'll probably find those tyres are past their best in terms of performance as the e-Niro puts a lot of torque through its front wheels.

You should be able to find all-season tyres quite easily for it - there are a number of brands making EV-specific all-season tyres now with improved rolling resistance (increasing range). Regular Michelin Cross Climates will do the job well, but be prepared for a loss of range of about five per cent because they are more resistant to roll.
