How long would they last on a truck that is driven to the trail and sees some street time? I've read all kinds of varying reports as to how long they would last, with a couple of people that've actually ran them saying they would last a long time and didn't wear down much at all in the 5k-10k miles they had ran them. I'm concerned that I'd buy these and then they would melt off in less than a year and not be nearly as street friendly as picking up a set of 33/12.5 generic mud tires. Also, how bad are they on the street? :corn:
