Steering wheel shimmies at 50-70mph. Have had tires rotated, tires replaced, front end aligned, brake rotors replaced still the shimmy is there and have been told that the big tires 18"rims 235/75 may partially been the problem. What? why would Ford use a tire that is too big? and cause the steering wheel to shake and shimmy. Have had an independent shop look at truck and can find nothing wrong, but I have never had a vehicle have such a noticeable shimmy in the steering wheel. Very unsettling feeling.
