The max pressure on the sidewall is the maximum safe limit, even that will have a safety margin applied. An engineer would never build a bridge that can withstand 22 tonnes and then put a 22 ton load limit sign on it. A 22 tonne safe load bridge would have an actual load rating in the 30 ton range.
Similarly, 44PSI is the safe limit, taking into account an acceptable fudge factor. The max PSI is there to be used (primarily by people who load their vehicles to max GVM [which will also have a safety margin]).
Having said all that, a lot of new tyres no longer have any PSI recommendations on the sidewall.
