That means in cooler weather putting more air in and in the summer putting less air in.
Two different things.
Adjusting inflation when the tires have been run i.e. when tire is not "cold" is the wrong thing to do.
Trailers should use the "cold" inflation on the tire sidewall to lower Interply. You should also confirm the load is no greater than 85% of the tire capacity when the trailer is loaded to its heaviest.
Again no messing around or adjusting inflation is necessary.
Be sure you understand what tire engineers mean by "cold inflation" Read my blog or read the reference manuals from the tire companies. Even many trailerowner's manuals cover the topic correctly.
