I have had my truck aligned, my tires/wheels indexed, road force balanced and I am still getting a slight shimmy at 55-65mph in the front end. Every mechanic that I talk to tells me that 35's, let alone MT's, on a 1500 will never be perfect due to the size and tread pattern. Any thoughts.....I am thinking about trying dynamic balancing with beads next. The shake is not terrible, but i want it to ride like it does from 0-50mph.....smooth.

 

Try getting some hub centering rings. They center the wheel on the hub instead of using the taper of the lugnuts to center the wheel
