Okay, I'm back from the motorsickle foolishness. Shaken, stirred a little, and thoroughly chilled.
Tires: Yours look good in the pics, so maybe you won't be doing anything with them for a while. Mine were rotten, so I set about looking for replacements for the original 7.50 - 17". I wanted radials, but what I found was mostly nothing. The only choices were bias ply, at vastly inflated prices. I considered them, but soon enough came to the conclusion that since my truck was to be road iron instead of an occasionally-driven museum piece, I had to go with my instinct as a trucker and upgrade all the way around. What was readily available and not overpriced was 235/80R16 tubeless. Superior in every respect except for originality. I had to change the rims as well, and found used aluminum rims which pleased me for the same reasons. Painted 'em black for effect

Those are some gnarly looking skins you have on your drive axle, Grendel. They look tactical. Are they?
