20.000 miles on my Nokian WR G2s and they barely wearing...Great on snow ,rain and slush, they were actually designed for slush, believe or or not..Had some hot summer this year in NJ and Nokians performed beautifully,little on the sift side , but I just keep them at 44-rear and 35 front.One thing though, about off road driving , that you want to do with them...I did many trips on steep hills and winding gravel roads and they pack with little pebbles like CRAZY, almost every single sipping was filed with stones on every adventure,and simple driving on deep mud ruts might end up with winching yourself out of being stuck simply coused by completely caked up tires with mud.They might perform well on rocks, but I have no experience on that surface.Wr G2 are excellent tires for winter and all weather driving,but off road tires they are not..
