There's no such thing as a free lunch. I saw a video on YouTube (maybe Jason on Engineering Explained?) that pointed out three crucial differences between electric vehicles and ICE vehicles. First, the rolling resistance of the set of tires is CRITICAL to energy efficiency on BEVs. All other factors being equal, the rubber for tires used on BEVs must be harder than that for ICEs to minimize rolling resistance and maximize range. And the wider and or taller the tire, the higher the rolling resistance so equipping a BEV with wider 21 inch wheels will significantly reduce efficiency over narrower 19 inch wheels. Second, because BEVs are so effective at putting torque to the wheels and tires, any given choice of rubber compound for a tire will have a much shorter lifespan when used on an electric vehicle. Finally, for any arbitrary size of vehicle, the BEV version is going to be SIGNIFICANTLY heavier than the ICE version which also requires more strength in the sidewalls of the tires on the BEV, meaning more material has to go into each tire used for a BEV.

Oh, and since wear on tires produces a stream of finely ground particles made up of whatever the tire was made from, the higher wear on BEV tires produces more of that pollution than equivalent tires on non-BEV vehicles.
