I enjoy old GMC and Dodge trucks. Currently I have a '52 power wagon I just finished restoring.
I have had a problem with vibration and the sensation of a slight hopping effect ever since my resto was done when driving on the road. Off road I do not notice it. I have 9 X 16 bias Power Kings mounted on the stock Budd wheels. They have an aggressive lug pattern.
The vibration and shaking seemed to be noticed especially above 25 mph, and was present after they were hot and the flat spot gone.
After researching this, I took the power wagon to a place over in Easton, Maryland (Elliott-Wilson Trucks) that had a tire lathe. They found I had about 1/4" run out with the tires on average. The picture is of the mechanic with the tire lathe or truer in action . After this was done he was able to balance things without difficulty.
A considerable improvement was noticed in the ride immediately afterword.
