can you put 20 x9 wheels in a E350 super duty 2008, designed for 16 wheels?”
The specifications for your vehicle call for a 245/75 16 tire size, according to Tire Rack, an online merchant that sells tires, wheels, and wheel packages. When you can use another rim with a particular vehicle, they will list the compatible sizes, e.g, my car takes a 16″ stock rim, but there are 17s and 18s that will bolt right onto the car without modifications. For an ’08 E350, they don’t show any. http://www.tirerack.com/tires/SelectTireSize.jsp?autoMake=Ford&autoModel=Econoline+E350&autoYear=2008&autoModClar= This is not to say a custom shop couldn’t outfit the truck with specialty wheels. This would involve rolling out your fenders to accommodate a wider track, and probably, modifying your suspension.
