It is very common for trailer tires to not be balanced ... every camper I've ever looked at has been shipped from the factory without the tires balanced. If you do balance your trailer tires, most trailers center the rim on the lugs, not on the hub, it is important the tire dealer balances off the lugs in this case ... if they balance off the hub you don't accomplish much (or make the balance worse) as you will have balanced on a different center than the wheel runs on when installed on the trailer ... the dealer needs to use a pin plate adapter to balance these.
Yeah with the hubs not machine balanced balancing the tires can actually create more imbalance. Plus steel trailer wheels lug holes are production stamped and may not be concentric with the tire bead seat flange.
Having owned several boat trailers/one TT/three 5th wheel RV trailers and put over a dozen other GN/pintle and bumper pull trailers in commercial service using the same size tires/wheels and axles we RV with, I've never had a tire balanced on a trailer.
Now... I have had tires with tread belt separation issues that would cause vibration. I watch all tires for any odd wear issues which can be caused by worn suspension parts/loose bearings/alignment issues/bent axle or stub/etc.
