Don per your link to the trailer specs what you are doing is listing the dry weight for pin weight, the dry weight for the trailer is 12750. The total load carring capacity is 3250 lbs. All this weight will not go on the axels. they show the pin weight at 20.4%. Using this same formula for gross weight the pin weight would go up to 3840 (16000 x 20.4%). This would leave 12160 left on the axels. This is a safe margin if your trailer is loaded to max and the weight distributed correctly. When you load the trailer to your normal use then weigh the pin and axel weights at a truck scale. You are safe if loaded correctly although I have this same weight and I made them upgrade to G rated tires even though the factory rep explained these facts to me. I had to pay a good bit more but that was for my satisfaction not because I had to. As listed the trailer is safe for E rated tires.
