What PSI should BMX tires be?

Having said that, my recommendation is around 80 PSI. Many people ride skateparks with much harder tires, sometimes around 100 PSI, 

but I think 80 PSI is great for the vast majority of people. 

It'll be a little less forgiving on hard drops but the speed and agility of your bike will be much better.
