I don't think balancing is necessary unless you feel vibration. Typical car tires weight 25 lbs and have a circumference of 83". 245/70-19.5 tires weigh 75 lbs and have a circumference of 106". A 2 oz imbalance on a car tire is very noticeable at 60mph but I doubt you could ever feel a 2 oz imbalance a RV tire @ 60mph.
