vibration at highway speed.

I'm getting vibration from my 17 transmitted to my TV. Feels like an unbalanced tire or wheel. I had the bearings repacked prior to my last trip and I had new wheels and tires installed. One tire seemed more worn out than the other. I don't feel the tires were very old but I could see some unroundness in my rear view mirror. I still feel the vibration in the TV. It seems to shake momentarily the stop momentarily. It's not severe but I do seen indications of things have been vibrating in the trailer. Hinge pins sliding out and the inverter door always open as well as things sliding around. Any ideas what causes this?

Sometimes they do not balance tires properly, which can cause intermittent vibrations. This can cause disarray inside.

In a past post someone had this problem and discovered it was caused by the cover on the front storage box. The added a thicker gasket & it fixed the problem.

In this part of the world trailer wheel balancing isn't common. When getting tire quotes I ask what their balancing charge is and it's either we don't balance trailer tires or the same as car wheel balancing followed up with "we don't normally balance trailer tires."

If you think that you can actually see some out of roundness jack up the wheel. Place a block of wood near it and turn the wheel. See how much gap there is between the tire nearest the block and 180* away.

You might also can see if there is any play in the wheels. Jack the trailer up, grab hold of the tire and see if there is any play,can you rock the tire. The bearings might have some how loosened up on you. My daughter had that happen to her once. Just a thought

Thanks everybody. I'm starting to think I am experiencing two different issues.
First, I must of had a bent wheel or tire that the cords pulled. Then after getting new wheels and tires I don't think they balanced them as I see no indication of any weights. I'm going to take it into the tire shop before my next trip. I was initially concerned that there was some kind of major issue but I am now of a mind I need to get tires and wheels balanced or rebalanced. We'll see.
