Why would the tyres be more expensive? Something like ID.3 or MG4 use normal tyres no different than ones you'd put on your normal Fiesta, they aren't any more expensive. The increased tyre wear is a problem but only in that it's directly linked with how heavy your foot is, and EVs make it much easier to have a heavy foot as you don't get any typical downsides of heavy acceleration you'd get in a petrol/diesel car.
