They have been great tires for me as well. Have about 30,000 on them and they still have tread left. Not down to the wear indicators yet, but the blades are almost all gone and they are hydroplanning more than I would like. One issue I had with these is the non-skid (tread depth) isnt very deep to start, not like most A/T tires (around 10/32 instead of 13-14/32). Slight noise increase, but not much. Handle suprisingly well even with the larger P285/60R18 size. Good grip in all conditions. They are getting a little noiser with wear, but have worn very evenly. Guess the only other issue is the ride. They larger size increase the pneumatic stiffness (more air volume) but also these tires have a very square mold shape (profile) which isnt very good for ride (impacts are really "sharp" and pronounced) moreso with wear since the tread blocks are stiffening with less of them remaining. Awesome looking tire, best as far as Im concerned. Might try the P285/60R18 Summitomo tires next.
