Tires are quiet on highway use (as all terrains)as compared to other mud tires I had, put 12k miles on, but tread is still near new. bfg km before, bfg km2 now, and bfg km2 later. Very happy with these tires...love the look, love the brand name, love the service tires provide. Price is ok comparing to other brands. I am totally a bfgoodrich buyer/user. Say no more.
