2007 BMW 328XI Wheels Problems

I JUST PURCHASED A 2007 USED BMW 328XI WITH ~45K MILES. ONE WEEK TO THE DATE OF PURCHASE, THE TIRE PRESSURE WARNING LIGHT CAME ON IN THE CAR.

THERE ARE A NUMBER OF PROBLEMS WITH THIS ARGUMENT. FIRST, THE RATIONALE FOR ELIMINATING A SPARE TIRE IS FLAWED AND UNSAFE: A SPARE PROVIDES DRIVERS WITH AN EXTRA WHEEL ' INCLUDING BOTH TIRE AND RIM, IN CASE SOMETHING HAPPENS WITH EITHER COMPONENT. ELIMINATING THE SPARE BECAUSE A CAR HAS RFTS (RUN FLAT TIRES) FAILS TO TAKE INTO CONSIDERATION THAT THE WHEELS OF THE CAR CAN ALSO SUFFER DAMAGE TO THE POINT OF IMMOBILIZING THE VEHICLE. THIS IS AN IMPORTANT SAFETY HAZARD THAT WOULD BE EASILY SOLVED WITH A SPARE TIRE. SECOND, AFTER RESEARCHING ABOUT RFTS I...
