When first into the Motorhome thing, I learned about Equal balancing powder.
A bag of powder is left inside the tire and it breaks and spreads in the first 100 miles or so. (this is not a knowledgeable explanation.
)
The powder then provides balancing of the tire.
Some folks use balancing beads because they do not plug up the tire valve like the powder might.
Here in the Southwest we have not experienced any tire valve problems with the powder.
There are many other forms of tire balancing available. But I do know that except for a bad batch of rear tires which could not be balanced, we have never needed to balance our CC rear duals.
We have a great rattle free rig that is 26 years old this month with 108,000 miles on the odometer.
