Depends on the look you want. Period correct could mean wider/taller all the way around or staggered skinnies/fatties front to rear. Biggest mistake (for my taste only) is to go wide at the expense of diameter (i.e. lower aspect ratio #, but nothing else. If you go with a lower aspect ratio number - which most folks equate to "wider"... (50 rather than 70), you need to also increase diameter (like a 275 rather than a 235) - or you'll end up with a fat little donut. A small (or smaller than stock) dia tire looks lost in these big wheelwells.

Here are the only options I'd go with if it were my truck:

Same all the way around:
1) 255/70/15 (my first choice)
2) 275/60/15 (my 2nd choice - but this is a pretty meaty approach - to me looks great in back, but can sometimes look too big on the front.

Staggered:
1) 235/75/15 front and 265/70/15 back
1) 215/75/15 front and 255/70/15 back (best for lowered+staggered in my opinion)

Are you lowering the truck? If so, I'd steer toward the smaller #/s as it's not as hard to make the wheelwell look full on a lowered truck.
