how to determine proper tire inflation pressure for on-road riding?

[John J Fisher]

What happened to looking on the tire for reading the tire pressure and put it somewhere near that but not over it? I have just entered the on/off road world, but thats what we did on the street. My 2000 KLR650 manual says 21psi for front and 29 for rear. The numbers below are higher than that. That would seem to me to be dangerous, but just a dirt newbie, so excuse my ignorance.
