Well there isnt much info on the new goodyear authoritys A/T... They are only available at walmart though and i dont know how you feel about buying a "walmart special tire" I like them because they are a aggressive tire, but still an A/T tire. My only problem i have seen about them so far is there load range for my size i want 265/70/17 is D or E i dont remember but its too much i think.. You can also look at BFgoodrich A/T's, or if you want more aggressive
tread, then go with the T/M's the first gen is cheaper... You can check out this thread for more ideas...
