Ok, I found a place that has some 19.5" wheels. What is the best way to check the fit? Drive the truck out there, jack up a wheel, pop the old one off and try out the new? I'll deal with tires after I get the wheels as the wheels are obviously more important.
I can't run the 19.5" radial in the front and the old 18X5" on the duallies can I? My instinct is no, but if they're direct replacements, maybe it is a possibility???
