correct, bmw always used wheel speed sensors and never had sensors on the wheels.
also, the falken 452's are not run flat tires even though that has nothing to do with it.
make sure your tires are correctly balanced and they all have the same psi (or around the same psi) and run the tire pressure reset properly. read the manual. my dad has an e90 and the manual tells you exactly how to do it.
