NBA rules dictate that basketballs should be inflated to between 7.5 and 8.5 pounds per square inch. If the basketball is inflated below this level, it won’t bounce correctly.
How do you know if your basketball has enough air?
Hold the ball up to your face and slowly let it drop. If the bottom of the ball bounces up past your waist or slightly higher, then it is fully pumped. If the basketball bounces up close to the chest, it means it has too much air. If it does not bounce up to the waist, it means there is not enough air.
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?
An overinflated ball can be bad as well. It will bounce too high when you dribble, bank too hard off the backboard and bounce passes will go farther than you intend them to go. This is why it is important to have your basketball inflated to the specified pressure or at least near the specified pressure.
What PSI should a Spalding basketball be?
Spalding makes the game balls for the NBA and uses a rubber bladder wrapped in fiber with a leather outer casing (this is the part you see), and has a 29.5 in circumference. Regulation pressure for NBA games is between 7.5 and 8.5 psi.
Why is my basketball not bouncy?
Since the internal air pressure of the basketball decreases at a lower temperature, the impact of the ball with the ground will also have less effect when it hits the ground. By that, the basketball does not bounce high enough as it does at a higher temperature.
Do basketballs explode?
Although rare, a basketball can explode if it is stored at a temperature that is too cold or if it is over-inflated to a considerable level beyond the standard PSI. An exploding basketball can be very dangerous and can cause harm to those nearby.
Are NBA balls bigger than college?
The official size of the basketball used by the NBA is 29.5 inches in circumference. That’s the same size used throughout men’s college and high school basketball leagues. The WNBA uses a slightly smaller ball, measuring 28.5 inches in circumference. … An NBA basketball must be inflated to a pressure of 7.5 to 8.5 PSI.
Why do basketballs lose air?
Basketballs tend to lose a little air when left unused and through normal use over time. In order to bounce properly, basketballs need the right amount of air pressure. … To get the most out of your basketball it is very important to keep it at its recommended air pressure, and to inflate and deflate it correctly.
What is a Moisten needle?
The purpose of moistening the needle is to prevent the needle from damaging or pushing the valve into the bladder. Saliva is more viscous than water; which is better for being a lubricant.
How do you air up a ball without a needle?
Method #1Use Compressed Air to Pump Up Your Ball
Well, with a compressed air canister, you have the perfect solution. The small straw that comes with the canned air will fit inside the ball’s hole perfectly. I’d suggest doing small bursts of air since the can will chill up rather quickly.

How do you measure PSI for a ball?
Insert the needle into the ball’s valve. Ensure the needle is perpendicular to the surface of the ball. If you insert it at an angle, you could burst the ball. Read the pressure level on the gauge of your hand pump.
