you could probably look up the recommended torque settings... im not sure if tightening as much as you can by hand will surpass the torque applied by a mechanised wrench...

i just go as tight as i can without trying to go nuts... and always give them a quick check when i come back after a drive...

the key is making them tight enough to sit flush with the hub whilst the wheel is off the ground, then doing the full tighten when its on the ground
