There is a low railroad bridge in your town. One day you see a large truck stopped just before the underpass. When you asked the driver what has happened, the driver tells you that his truck is one inch higher than the indicated height of the opening. This is the only road to his destination.

What can he do to get through the underpass the easiest way?


As the tires of the truck has sufficient clearance between the inner and outer part of the tires via air gap. The tires can be deflated to decrease the height of the truck by one inch and the truck can pass through!!!
