the wider you go, the more wander out of them, and its not just these tires, my bfg's did this, my nittos, and the toyo mt's did also. they were all 12.50 wide and 33s and 35s. 265s shouldnt wander any
i had 285/75/16 bfgats before and no wander at all they where on two different trucks and had over 55k on them when i put the hankooks on and they are the same size 285/75/16 and there is some wander with them not a ton but enought that you know its there i only have about 2500 miles on them and still like them they have much better wet weather grip than the bfgs did
