Bought my Z4 in April this year, have done approx 3k miles since. Car is in today for its service and I have been told the two front tyres require replacement as they have dried out. Quick google suggests this is a thing for cars that do not move, 'a car that sits for a period of years will experience dry rot.' Car is 3 years old next month and has now done 36k miles. Anyone had this before, car is still under its 3 year manufacturer warranty and its years BMW approved used warranty. Has this happened to anyone else? Do I have any recourse?
