the "e" load rating makes the tire consierably heavier.. and considerably stronger when it comes to the sidewall.. so if you do hard offroading, the E load rating is probably best.. just looking for good all weather traction for on road.. you could probably get away with the lower one

i just noticed that all of the nittos listed were s speed rating.. are there higher? pretty sure the stock duelers were H speed rating, dropping two levels will probably affect your handling a decent amount
