How big is your bloody trailer to need that much pressure in the tires?!Or trailer. The tires on ours run at 80 PSI
Or how small are the tires?? 
If your trailer is running pneumatic tires (and mentioning their air pressure suggests that they are pneumatic) then unless the trailer's actually carrying at least a few heavy cars or something of a similar weight, or it's only running tires that're the same size as a kid's bicycle tires, then it's extremely unlikely that your tires really NEED that much air pressure in them for the load they're carrying, even if they might be safely capable of holding that much pressure in them for those (probably very few) instances when they might be carrying their maximum load!
Just cos the placard on their sidewall or in the maker's specs says they CAN hold that much air pressure to achieve their MAXIMUM LOAD capability, it doesn't mean they SHOULD be run at that pressure all the time, not unless they actually ARE carrying that maximum load!
Even my 22 tonne 3 axle dog trailer doesn't need that much air in its tires 90% of the time! 
Just Sayin!
