One advantage to the 305/70/16 is also the wider tread area for the section width...so, for example, the BFG AT ko in 305/70/16 is a full 33" in diameter, and has a tread width a bit wider than the traditional 33x12.5/15, with a slighly narrower section width.

The wider tread/increased contact patch with the narrower section width makes the 305/70/16 handle better than the 33x12.5/15 as well.
