tire wear on the outside tread

[tom woodward]

Just returned from another trip and noticed that my tires are wearing abnormally fast on the outside tread. These are 12 ply, high dollar tires (not CCP tires). It would appear that the camber is off a bit as there is not the same amount of wear across the rest of the tires, just the outside tread. All four tires have the same wear so I don't think rotating them would help. Is there a way to adjust the camber? We have a 5er 353RL High Country, 2015 model
