How much PSI does it take to pop a tennis ball?

So how long do tennis balls really last? Tennis balls will go bad after about 2 weeks or 3-4 playing sessions. Unopened tennis balls are kept in a pressurized tube to help them retain bounciness and firmness, but even those will expire after two years (due to very tiny leaks).
The best way to keep tennis balls pressurized is by leaving them in the can unopened. … Some players may keep tennis balls in the trunk of their car, but this is not a good place, so avoid it as much as possible. So unless you will be using the balls, don’t open the can and keep it at room temperatures.
Recreational Tennis: if you’re just playing tennis at a recreational level, a can of pressurised tennis balls could last anywhere from 1-4 weeks, depending on how much you use them. After that time, the balls will begin to lose their pressure and bounce.
