Here's my '72 with 4" lift and stock 235/85R16 tires and my '69 with 6" of lift and 35's.

35's are pretty much considered the size limit for half ton running gear, but there are plenty of guys running bigger tires on stock running gear. Board member 2wblazer runs 38's or 39's on his and he does wheel it. I've seen trucks with 44's on half ton gear, but it doesn't sound like a good idea to me.
