Don’t bother if you didn’t see it on your ball—not every manufacturer prints it on their basketballs. NBA recommends that the air pressure in a basketball must be between 7.5 and 8.5psi. You can use this standard measurement as a guide to get the required air pressure for your basketball.
The recommended air pressure for a basketball is 7.5 to 8.5 psi (pounds per square inch). That is also the NBA basketball air pressure recommendation. As you can see, there isn’t a fixed air pressure endorsement by the NBA, but you can use this recommendation as a guide to getting the right air pressure.
What Is the PSI of a Regulation NBA Basketball? A regulation NBA basketball must contain between 7 1/2 and 8 1/2 pounds of pressure per square inch, or PSI. The ball also must exhibit an official NBA approval mark. At the beginning of an NBA game, each team must have access to six balls during the warm-up period.
Conventional wisdom is that a basketball needs 8 psi to be properly inflated. A car tire, just for a comparison, needs 40 psi. Most basketballs have inflation instructions printed right on them.
For a 29.5″ basketball (mens) and a 28.5″ basketball (womens), the recommended air pressure range is 7 - 9 PSI. The irony is almost no one has a gauge to accurately check the PSI rating on a basketball while inflating it because most pumps aren’t equipped with a gauge and ones that are rarely give an accurate reading.
Basketballs are measured in PSI or pounds per square inch. A basketball should be about 8 PSI. For comparisons sake, a football needs between 12.5 and 13.5 pounds PSI, whereas a tennis ball needs a pressure of 14 PSI. A car tire has a pressure of 40 PSI! The higher the air pressure inside a basketball, the higher it will bounce.
An adult for assistance. 3 basketballs: 1 basketball at 8 psi, 1 basketball at 9 psi and 1 basketball at 6 psi (psi = pounds per square inch) 1 Air pump. 1 Pressure gauge. 1 “Yardstick” style tape measure. 2 Different surfaces: 1 wood surfac,; 1 concrete surface. Marker (mark each basketball with the correct psi)
For 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. Source:...
