MDW once drove our '66 bug 40 miles with a blown rear tire. Ive driven 10 miles or better on a flat. MDW has strict orders to drive the car to a place of safety before dealing with it. Call me or AAA from a safe place. Flats are no big deal provided you're not doing it in the break down lane or sticking out on a curve. I've seen plenty of flats within a mile or 2 of the next exit , often with a gas station. or at least a place to park.
