My past experience with F10 528 xi, the run flats did not last well and dealer recommended changing them at around 33K miles. Dealers generally err on the side of caution to make money
Eventually i got 4 new run flats from costco at 40K miles
Talking to some of my other friends, they all had to replace their run flats by 45K miles
