Hi, and welcome. My name isXXXXX you can replace your run flats with a regular tire but you will need to purchase a spare wheel and tire to place in the trunk in the event of a flat. Run flats are mainly used to reduce weight and increase trunk space. There is nothing special about the car that requires you to stay with the run flat tires.
Please let me know if you need have any further questions in regards XXXXX XXXXX tires. If you would please take a moment to rate my service today I would appreciate it.
