Direct Answer
The BMW iX most commonly uses 255/50R21 tires from the factory. Other factory fitments include 265/45R22. As an EV, the BMW iX runs heavier, so EV-grade or reinforced load ratings matter. Always confirm the exact size on your driver-door jamb, since trim and wheel package can change the fitment on a BMW iX.
