Watch this before you over-inflate your tyres
The video here shows how important it is to keep an eye on the pressure guage when you are inflating tyres, be it your bike, car, or any other vehicle. Over-inflating can cause serious harm. The video above, probably shot from a security cam of a garage, shows a person inflating a truck tyre. He seems to be oblivious of the fact that the tyre is getting over-inflated.
This results in a blast like situation, throwing the person who was filling air into air as he had one foot on the tyre. The other two person in the room, duck due to the sound of the blast. This can happen to anyone who over-inflates a tyre. (via Jalopnik)
