i've had mine for about 500 miles now and all i can really comment on at this point is the grip in the rain on the wet roads of washington , with it raining over the last week i've been trying to break them loose around corners and such, and i have failed, they will chirp but keep traction as if it was a hot day out, i'm really impressed, they balanced and mounted perfectly on my 4runner and i have zero vibes up to around 80-85 , meaning i don;t know if there are vibes beyond that becuase i didn't go faster then that.
i still run bfg at's on my '91 xj and have to say that these duratracs are far superior according to my butt gauge and i'm only talking DD here right now as i haven't been off road yet in the duratracs but having a far more aggresive tread patteren then the at's i would think they will be better in that since as well.
i was trying to decide between these and the toyo open country mt's and am happy with my choice, i'll pop back in here for time to time for reports on wear,mud and snow handling and any issues that may arise.
