On my 1997 4x4 dually i ran BFG commercial traction tires that lasted the longest. Everything was replaced with the front suspension before 100k miles. My best change was the control arms. I had watched a youtube video showing the front suspension under torque by placing in fourwheel drive , holding the brake and loading while another person held the camera. Even though i was unable to move the arm bushings witha bar to test using this method they flexed to the max therefore adding to bump steer and tire wear. The old bushing were visibly normal even though they were soft. Its cheaper to change the entire control arm as opposed to just bushings. And the tubular arms are much higher quality. Mine also had the PSC gearbox with brace and third gen trackbar upgrade.
