I am getting my first ever Z4 on Sunday, a 2011 2.5 sdrive23i M Sport. The current owner doesn't know if the car has run flat tyres or not. Is there a way of telling? If they are run flats, I have read here that they do not give as good a ride as regular tyres so I am thinking of changing. Does the tyre pressure warning system still work with regular tyres and will I need to get a spare?
Thanks
