Bias tires don't really balance very well. If you really want to balance them and have them stay balanced you would want to dynamically balance using balance beads or something equivilant.
I was told that the bias tires get flat spots on them when they sit for a period without moving. It did sit in my driveway for 2 months without moving. Ans also was told that the torsion bars had to brake in since it is a new trailer.

In cold weather, nylon bias ply tires, especially truck or trailer tires with many plies, can take a set when sitting overnight. It really hasn't been a problem for about 30 years or so.
I would consider the torsion bar break in thing a myth.
