I have all tires/wheels balanced.
I pay the tire tech $10 extra tip per tire, for showing me how well he has positioned the tire on the wheel to avoid egg rolling.
Each axle has Centramatic's.
Tires are on our RV's from 5 -10 years, depending upon what an owner feels is his comfort zone. (I target replacement of my tires at between 6-7 years of age.) So if you spread the cost of an $80 tip, and the costs of balancing to the shop, over those 6-7 years - well, it sure is not too much to do so:)!
Best to all, have fun, be safe,
