That is a lot of rubber. You have an alignment problem. There was a time when I would not have said that emphaticly but I found an alignment shop operator that knows what to do with the Dodge front suspension. The whole thing is that these front suspensions are just slightly bigged up car suspensions. For a number of years and in fact from the factory, I had pulling and also abnormal tire wear. This guy had to tweak my trucks a couple of times to get the pulling gone and stop the wear but they now will drive on loooooong trips without wearing out my arms as well as give good tire life.
