Should I Balance My New Tires?

Some are, some aren't. I've seen drums back in the old days that had balance weights on them and drilled rotors, but it's all about inertia. A brake rotor has only a very small fraction of the amount of inertia that a tire/wheel assembly has. I.E. A brake rotor could be 10x (for example) as out of balance as a tire before it has the same effect.

A trailer brake drum is only a couple of inches smaller than the typical location of wheel weights. Your 10x is nonsense. I have added more than 5 oz. of weight to the wheel to counter the effect of an unbalanced brake drum. Unless and until you check the balance of your brake drums, any discussion is just noise. You might get lucky and find that your drums are only out by an ounce or two. I balance the entire rotating assembly which includes the tire, wheel and hub/drum.
