Should you "balance" RV tires or "true" the wheels?

(Nov. 8, 2012) -- Many times the cause is not that the tire(s) is out of balance but that it is out of round. When repeated attempts to balance fail, what the tire tech should be doing is checking run-out on the tire to see if it is oval shaped and if it is, determine whether the lopsidedness can be corrected by rotating the tire 180 degrees on the wheel. Tires are seldom, if ever, perfectly round and the same is true for wheels.
