235/85/16 was the stock size on my D series 250 .. i,d think a W series truck would have had at least the same size if not bigger from the factory ?

i upsized to 265/75/16 on the factory steel rims, same height as the stock tires but about an inch wider.
They look big on a lowly 2wd but i think would be about perfect on a stock height 4x4 that,s used for work.
