The main thing with tire pressure is if you don't have much pressure in bmx tires doing all your tricks jumps and shit, when you're jumpin high or onto a ledge and hit really hard you'll most likely bottom out your tire which will do one of 3 things, put a hole in the tire (not the tube, but will make your tube bust eventually) from rubbing the side of the tire on the rim, bend your rims (not triple walled) if you hit very hard, or just straight out give you a pinch flat busting your tube and having to dish out $5 for a new tube every time you blow it like that. So all in all, keep em high pressurized, it'll vibrate like nuts and hurt your wrists when you first start doing that, but you just get used to putting more weight on your legs. And it does give a limit on the side of the tire for psi, but don't really pay attention to that, just keep give'n 'er until you can barely squeeze it with your hand at all.

Yeah that sounds good, the max psi on the tire is usually around 65 -70, but screw that, the wheel is practacally half flat then.

the higher psi, the lower the rolling resistance will be, thus, the ride will be smoother, and you should also roll for a longer way as well. also the higher the psi results in having a greater resistance to pinch-flats.

however, high psi's can make the ride a bit harsh, and landings hard.

low psi's in theory give better grip, but i wont explain why....they just do, this is why mountain bike riders often run quite low psi's

i run mine around 75-80 psi, i find that is a good comprimise.

There's more tire in contact with whatever surface you are riding on.

the side of my tire says 40psi or 45psi or something?
once i pumped it up super lots, i dont know what psi to though, and i rode it for a bit. i got off and went into a shop and the tube exploded :( took me like an hour to walk home.

so should i just go way past 40psi or something and pump it till its super hard to squeeze with my hand?

Well it was probably insanely high if that happened, probably like 100psi, but even so it shouldn't happend that easily, check the inside of your rim for a liner that covers the spoke tips, also check around your actual tire for holes.
