Just because a tire lasts as long doesn't mean it isn't wearing in different ways. EV specific tires are a lot different than their ICE counterparts.
This isn't "black PR". It's comparing apples and oranges. But throw non-EV tires on one and you'll definitely chew those tires up much more quickly [0][1][2][3].
The class of the Ioniq 5 isn't lighter than it's ICE competitors. It may be lighter than a larger SUV, but the tire changes drastically as the GVWR increases.
An Ioniq 5 can weigh over 1000lbs more than a Honda CR-V, for example (depending on trim & battery).
