had the ltx at2s on my 2013 2500. best road tire ive had. not good off the pavement or snow. took them off with 43,000 and while plenty of tread left they were starting to lose the wet traction. just put on nitto exo grapplers and so far im very happy with them. no wandering at all and quieter than i thought they were gonna be. i would give the duratracs some more time and let them break in a little to see if the wandering stops. i had 2 sets of tires do the same thing you are describing and once i got some miles on them they were fine
