What happens if you put too much air in your bike tires?

The higher pressure makes the bike feel fast but may actually be slowing you down! If the tire is too hard it will have a tendency to vibrate and bounce which increases rolling resistance and makes for an uncomfortable ride.

Is 50 psi too much for tires?
