How to search for tires?

Okay, I watched, most, of the video on balancing tires, and no where does he mention that many, perhaps most, trailer wheels are lug-centric, and almost no one will balance lug-centric wheels. I asked a guy at the tire dealer why they don't balance lug-centric wheels and he said they do. But they balance off the center which he said works fine. But if the wheel is balanced hub-centric, but mounts lug-centric, how is that fine? He just kept saying it's not a problem.

In theory, the wheels are machined using the center hole as center - and that includes the lug holes. So using the center hole is nearly the same as using the lugs for lug centric wheels.

Besides, there is a tolerance for balancing - which is why they have wheel weights in increments. The difference in balancing using incremental wheel weights is imperceptible to the user. And since trailers aren't designed to be ridden in, close enough is good enough!

I can see the idea, but my issue isn't with the tires/wheels, it's with the drums that the tires/wheels mount to. How precisely are they positioned in relation to the center ring? Nothing about those drums says "precision". :)
