Not sure yet on the wear, only got 300 miles on them...I had a 2009 with 35-12.50-17 BFG's; the Generals are 315-75-16 (34.6). DEFINITELY much quieter than the BFG's andnmuch more smoother ride than the BFG's. Did Webster's Pass in Breckenridge with my 2009 about a month ago...trying to get back up there with the 2012 before the weather changes. I can say that a 2012 with Pro Comp Extreme MT (35") rode a liitle less quiet than the Generals, but seemed to be just as smooth. So far really Enjoying them.
