I had a tire pressure warning come up on screen during the drive yesterday but the on board computer said I can resume the drive as the car is equipped with run-flat tires.

Well, it turns out that these Pirelli tires are not run flats and the pressure dropped quickly and below critical. The car has no spare tire, no tire-puncture fix solutions in place, no high-jack or even a pump included.

The car is the “Ultimate pack”… Does this sound normal?

Bought the car new from BMW.

    You can’t have run flats on M models. It’s not part of the official configuration for M models.

      Maybe some dealerships swap out the regular for RF at the customer’s request? Some folks (not me) prefer to have RFT since they want to continue driving to a repair shop if they get a flat/puncture. I have RFT on my X3 M40i and once had a nail/screw in a tire. Pressure dropped to low 20s. I drove about 10 miles doing 30-40mph max; got a plug installed, and the tire has been fine the last 1.5yrs. When these OEM tires wear out, im getting regular HP all seasons tires.
