Hard to imagine hey that size is only 12mm more than stock.

And also interesting that my 265/60/R18 B'stone D697 fitted easily without deflation.

Me too - I didn't even think about it or notice any difficulty.
I wonder why the difference...?

Weird as both brands have the same diameter as per their specs.

A 245/70/17 will fit fully inflated no worries. Which is also the same diameter.

Maybe it is the extra rubber in the KO2;)

Tread depth on the BFG's is 16mm new. What do the 697's have?

I had a general Grabber AT tyre in 255/55/19 and compared to the Highway tyres in the same size it was a larger diameter due simply to the tread depth.

That might explain the difference?

Here are some photos of the right rear tyre as promised above. You can see the two major stone chips but not too much other damage after 14,000km on very rough and stony roads.
