What BMW approves
BMW-approved tires carry a star on the sidewall.
The star means BMW signed off on that exact tire for that car. Many BMWs also leave the factory on run-flats, marked RSC or with the maker's own code such as ZP or MOE, and BMW's own advice is not to mix run-flat and standard tires on the same car.
Brands that carry the approval
Written on the sidewall as: Pirelli P Zero (★), Continental PremiumContact 6 (★).

Every US car built since 2003 carries this placard. It also gives the pressures, which the sidewall does not: the number molded into the tire is the maximum it can hold, not what your car wants.
What those tires cost
BMW iX tires: common questions
What size tires does a BMW iX take?
The most common original size is 255/50R20. Other model years and trims use different sizes, so check the list on this page and confirm against the sticker inside your driver's door.

You can, within limits: the overall diameter should stay within about 3 percent of the original, and the load index and speed rating must meet or exceed the door placard. Anything further changes your speedometer reading and can rub at full lock.
