That said, wear can be substantially mitigated by how the tyres are designed and manufactured, particularly the tread compounds. But, long-wearing compounds are generally inversely correlated with grip, so there is a balance to be found there.
There is also the fact that manufactured seem to absolutely not GAF about weight anymore, even on internal-combustion cars, so the ICE-vs-EV weight difference may be narrowing.
But yes, tires for heavier cars are more expensive by themselves, and ceteris paribus, wear faster, so can definitely be a significant expense factor over the 5-10 year terms in this article and discussion.
Especially considering that it's common knowledge in motorsports (although evidently less common than it should be) that more power only increases acceleration performance, but lighter weight increases performance of acceleration, braking, cornering, and tyre wear! Plus, reducing weight is compounding; take out one chunk of mass, and other components can also be made lighter, e.g., reduce the body mass, and you can fit lighter suspension components, brakes, wheels, tires, etc., and the light-weighting compounds.
I drive year-round in a cold/hot climate with winter tires (because I'm too lazy to do the seasonal swap out). It is pretty hard on winter tires to run them in 100F days. But, so far, in the last 7 years of winter tires, I've gone through 2 sets.
Tires are the least of my annoyances with Tesla. Lack of quality control, lack of good customer service, and a fascist dictator at the helm have all prevented me from considering another Telsa.
