On the other hand, if you inflate the strut too much, you won't have steering at ground as the lock stays engaged. I've seen this once, a pilot with the good habit of pulling back the yoke during taxi on soft field to prevent stress on the nose leg, but he didn't know the strut was overinflated. From the moment he gave some throttle the prop wash over the elevator raised the nose even further and the steering locked. This cam-lock system in the nose strut is the same on big pax jets as on cessna's by the way.
And to aviatorchina, the best method to center steering after a turn on runway line-up is to taxi down the center line in a straight line for a few meters.
