4 wheel trailer, standard equipment with 21SPX. One of the rear tires picked up a screw and had to be replaced, and new tire has printed on it 'Inflate to 65 PSI'. However, the other three say 50 PSI Max, and the trailer sticker lists load capacity at 50 PSI (though it doesn't say 50 PSI MAX). So, do I inflate the oddball to 65 PSI, or keep it at 50 PSI like the rest? (It's 50 miles to the launch, maybe 5x/year, probably less than 1K on the other three). Thanks!
