Yes, balancing can make it worse or better. If the heavy spot of the tire and the drum were opposite each other, balancing will make it worse. If you never checked your drums for balance, you have no idea and shouldn't jump to conclusions.
That depends..
The drum has a much smaller diameter AND MASS than the tire.
Car drums and rotors ARE "balanced", pretty easy to check to see if the drums have been balanced. Typically balancing on drums consists of the manufacturer either drilling /counter sinking into the heavy spot or adding a permanent weight (spot weld) to the light side.
Balancing drums on a trailer is not going to DRAMATICALLY change anything with the trailer due to the small diameter and MAS of the drum,
Balancing the tire on the other hand may or may not make any noticeable change since you are not RIDING in the trailer.
I have run trailer tires balanced AND unbalanced and FOUND NO DIFFERENCE in how the trailer tows or feels. How ever with that said, balancing CAN potentially add some life to the trailer tires since it will REDUCE the BOUNCING of the tires if they are far out of balance.
OK, I understand that you have never checked the balance of the assembly. So why comment?
I guess YOU don't have a clue about MASS and DIAMETER of said mass..
Why should YOU comment?
A drum is approx 10" in diameter and weighs about 25 lbs.
A tire mounted on a rim will weigh in 45 plus lbs, and the outer diameter will be 30 plus inches.
The MAJORITY of the tire mass IS ON THE TREAD.
Not to mention the outside diameter of the TIRE IS ROTATING at a much higher rate than the INSIDE diameter of the DRUM.
Rotation speed plus MASS makes a huge difference, not to mention the further out the imbalance the more pronounced the effect.
Balancing the drum has very little "effect" overall and balancing the TIRE CAN and will have more effect overall.
Simple basic high school physics class stuff.. Did YOU sleep through that class?
I suppose you balance your bearings and grease?
