Honestly I don't think they wear too bad... I have about 10,000 miles on mine and they are at about 50-60 percent tread left. The first 25 percent of the thread seemed to wear really fast but slowed down after that. They've done great offroad for me too. For the price I paid for them brand new im happy with them.
My friend also had them on his 1500 ram and they wore well for him too.. He put about 20,000 miles and them and then sold them to my friend and he's put about 5,000 on them so far and they still have decent life left in them.
