I was just now washing the car and noticed that one side of my front tyre has shredded (see pic). The tyre is a P Zero 275/30 20r run flat. I need to get to the tyre place but its 7 miles away. Obviously I would drive very slowly but does anyone know how dangerous it is for me to drive the 7 miles. I hoping that as it is a run flat it will get me there OK.
