Well, with 4 tires, 225 to 235 adds up to almost 2 inches ... and in slush
and so on at speed, it's enough to affect my puny little 3000 lb Cherokee.
As to the heavier trucks, no problem I'm sure. Now if I went to 245s, yikes.

so - you're saying that with the narrow footprint there is probably more
bite
to the footprint - ala the psi of the footprint -
vs the wider tire that will distribute the weight more
and not take a bite out of snow, ice, slush, etc -

hmmmm - any other thoughts on going from the 75 to the 70 (225 to the
245)

Re: GC tires - 225/75 vs 245/70 (R16)
 

The 75 or 70 is the ratio of the height to the width ... or vice versa ... I
think :-) So if the width is 235 (mm), and the ratio is 70, then the height
is 70 % of 235 (mm) and if 75, then 75% of 235. I dunno ... some people like
the look of a 70, or 75 ... apart from that, unless the diameter becomes so
drastic so as to affect braking, I don't see that it's a consideration. I
myself "like the look" of my 235/75 Michelins (summer tires) on my Cherokee.
