Nicest tire size for 85 crewcab longbed?

[Wincks2]

Old Smokey



has 265/75 R16 on the back and 245/75 R16 on the front. Have to change the front ones. Would like all four tires to be the same size. Will probably go with 265/75 R16 on the front to match the back. Buuuuuuut, I could get carried away and put four tires of a different size on her and am open to suggestions No lifting or lowering, but on tire size I'm open to suggestions.

Her primary purpose in life will be pulling the 19 ft long 4,000 lb trailer you can see in the background along highways. She will have a white cap on her bed. The black bug shield has been removed from the hood front and will probably stay off. The sun visor thing above the windshield will probably stay. Those are plastic or aluminum hub caps on the front and I guess I may get ones to match for the back or maybe a new set of four. I would like to be able to turn her front tires all the way in both directions and go over road bumps without the tires touching the fenders. She is a two wheel drive truck.

So, what tire size would you suggest would be best for her purpose and look really good on her? Assuming I can get functional tires of every size, I guess I am asking about form more than function. Or are the 265/75 R16 nice looking enough to save the expense of the third and fourth new tires?
