How much air does a basketball need?

An NBA regulation ball is inflated to between 7.5 and 8.5 psi. By regulating a basketball’s air pressure, the NBA can ensure fair playing conditions. As this activity illustrated, the ball’s internal air pressure determines how it bounces.

Can you over pump a basketball?
