My rear tire went (actually, I spun the tire on the rim, tearing the valve stem out of the tube), and the rear end went to the left, turned the forks to the left to the stop, and rode it (sliding sidewise) to a stop like that, with a passenger on the back.
I have ridden for over 20 years and never had a blow out, only a flat. This does not mean your experience will be the same as mine or any other rider. You can alway buy a retired police HD, they have run flat tires on them. Meaning they will run on a flat.
