[77-383 Step]

I would agree with Zoomad and Bus. Loading a trailer, even with a 3/4 or 1 ton truck can make a huge difference. While there are problems with loading the tongue too heavy, I think it is more dangerous to load the tongue too light. If you load the trailer with all of the weight on the back, it can cause the trailer to whiplash like mad at highway speeds. But you do need to get rid of those tires, or at lest stop towing until you do.
