But the math really isn't that critical with the beads. Any extra beads will distribute themselves evenly around the tire.
The 5.5 oz. mentioned was needed at the normal location on the wheel. I presented this to show the fallacy of dumping a substance in a tire in the hopes of getting perfect balance. Since nobody checks the drum balance and has no clue where the heavy spot on the tire or drum is located, they have no idea of the amount required.
I static balance the assemblies or use my strobe on the vehicle to get them right.

What does everybody do here? They are for 29ft 5th wheel 225-75-15
Find another dealer, if they're giving you such [email protected] advice. Anything that rotates at that kind of speed needs to be balanced. I've seen more than a few trailers going down the road with wheels bouncing off the ground. The worst was a TT that had the left rear tire bouncing, I kid you not, at least 4" off the ground. I have no clue as to why the driver couldn't feel that. On top of that, he was towing at about 70-75 mph.

Often the weights on the inside will not be in the same location as the outside. That is how the dynamic balance is achieved.
I know Discount balances that way; both inside and outside weights and not necessarily in the same location, as you say.

Tires jumping up and down on a trailer is the result of severe flat spots from locking brakes......tread delam issues/etc and no amount of weights would ever balance the tire.
Sound like a experienced tire dealer that has been around the trailering world to me.
