I pumped up a Basketball to 60 PSI, at about 55 it started making crackling noises, when I got to 60 PSI the crackling noise was constant and within 2 seconds of reaching 60 PSI the ball exploded. The ball was a Wilson Optima Rubber Basketball .

∙ 12y agoFor NBA regulation basketballs, the requirement is between 7.5 and 8.5 psi. Your basketball may vary, and if it does, the packaging should state how much psi should be used.

The gauge on your pump, if you have one.
About 8 PSI
7.5 to 8.5 psi
A concrete strength of 3500 PSI should be just right for a basketball court.
Somewhere between 8-10 PSI
A pressure gauge is commonly used to measure pounds per square inch (psi). It typically consists of a dial or digital display that shows the pressure being applied to the instrument's sensor.
In basketball you score points, not goals.
The boiling point of ethane at 175 psi is approximately 137°F (58°C).
Assuming standard atmospheric pressure of 14.7 psi, the pressure difference in the basketball is 5.3 psi. To estimate the volume of air in the basketball, you'd need the basketball's size, as well as assumptions about temperature and ideal gas behavior. This volume would be significantly larger in standard conditions than when pressurized.

The "Big Bang" explosion I hate doing science homework. This is what my homework is. lol
The two point shot has always existed in basketball.
