I am on my second set of KO2's on my RAM 1500. The first set was perfect! Easy to balance, no issues...I just wore them out at about 50K miles. The second set has been a nightmare to balance. I bought them at Sam's Club in Colorado Springs, and they have been helpful, but to get them balanced the last time, (2 weeks ago) I went to Les Schwab and paid $64 for a regular balance job. Expensive, but the job was done right.
For reference, I drive in similar conditions that the OP does in this area...pavement, dirt road, snow, hunting trips in the mountains, towing a trailer. I love the KO2's for their traction and sidewalls, but hate the balance issues.
When talking to the tech that did the balancing at Les Schwab, he said he would get Toyo or Nitto if it was his truck. If I had bought the KO2's from Les Schwab, they would have done the road force balancing in the cost of the purchase. Food for thought.
