Your tires are past their date and will make you very sad. Start with getting good tires first. 2016 tires are about 1 year too old and not to be trusted. No matter how much tread is left. Ask me how I know (and others too).

To be clear "Roadforce" isn't a different kind of balancing.
It is a feature on Hunter machines that measures the radial and lateral runout of the tire and wheel assembly (or bare rim).
Assuming the runout is within tolerance, the machine simply tells you so and you balance as normal.
If the runout is excessive then it proposes repositioning the tire on the wheel to match the "high spot" on the tire with the "low spot" on the wheel to minimize the total runout of the assembly.
This involves breaking the beads and rotating the tire on the rim.
It is worth throwing the tires on the machine to see what is measures the runout to be. Then you can rule it out or take corrective action.
Shouldn't cost very much to just throw them on the machine and give them one spin and get a reading.
They should also have an adapter for the machine that allows you to bolt the wheel to it for stud piloted wheels (stud centric).

thanks for all the help guys.

I have that same trailer but without the rock guard/deflector. I tow it with a 958TT. I've never had the vibration issue you describe,
I have also always used one of these hitch stabilizer pieces - so not sure if that makes any difference or not but its cheap and easy and worth a shot for you -

Well oddly pulling the shield reduced the vibration about 75% when combined wirh the hitch stabilizer. im still not 100% satisfied but its way better

Can you tell me what you found out on the shield removal and whether is solved the problem.? I have a new Aluma 8218 tilt that I bought the end of last year. It towed fine. No vibrations with a smooth ride at all speeds. I added a stone guard and tool box a few months ago. All Aluma accessorizes On my first time out with a loaded trailer and empty I NOW get those same issues with vibrations. Some times it will ride smooth and then when I travel down the road and it does it again. For no real rhyme or reason. Nothing else was changed on the truck or trailer.

I never got around to removing mine. I’m pulling a lighter (2800 vs 3800) car now, and it seems to be less of an issue. I am going to try to cut about a foot off of the shield so I can see behind me. I have the high rise shield that is about 43” above the deck.

Ive towed a few times without the shield and while definitely better, the vibration is still there. When its smooth its a dream to pull but with the vibe its pretty annoying. A shame

so to update this thread, I balanced the tires, and tried moving the car all the way forward and back on the trailer. Further back seemed to help a bit (but was bouncy) temporarily, but then after about 2 hours or so, it was back to its old self. Checked and greased bearings, adjusted brakes, etc. To me this is really not acceptable. My last option is to take it to a trailer specific shop (if they would ever call me back 
) and if they can't help then I have to sell it. It makes tows over an hour or so unbearable. Aluma was a bit helpful at first, but no longer responds to my emails. I'm not sure how a platform with wheels can be this bad, but here we are. extremely frustrating.
