its always good to have a $5 tire repair kit. it has a metal tool and rubber inserts. a one min job and you can even carry on driving home from malaysia. that is, if its a small puncture caused by a small nail. But pls do the diy repair with safety in mind.
For a major cut or a puncture caused by a large object, do not attempt to pull out the object as it can send the object (eg a big metal bolt) fly in any direction.
Best call AA or refer to the insurance document for road assistance service number. Remember, many people died on the highway while fixing a tire. the on coming traffic just sweep him/her off the feet and kill the person instantly.
