what tires?
 

Right now I have a set of Yokahama Geolander A/T. I have about 16,000 miles on them and there is maybe 1/4" tread left. I am severly dissapointed with how they are wearing. I was told it's a dually thing to wear hard on tires but I'm not sure. So my question is, what is a good, long lasting tire (about 40,000 miles)? I'm going to see what the tire place I bought them from has to say. A guy I work with suggested Goodyear dura trac. Has any one run these on a dually?
Thanks, Geoff
