Where should you park when your tire suddenly deflates on a highway?

First and foremost, put a caution sign at the back of your car if you're not given enough time to park, then call for a tow truck if you don't know how to change a tire. 

But if you do have enough time, pull over to the side, where vehicles are rarely going and follow the above steps.

Put on your hazards and pull over immediately.
