The width is the 225/235/245 number. The 70/75 number is the height of the
sidewall.

A 225/65, 225/70, and 225/75 are all the same width. The difference in these
tires will be the amount of sidewall, and the overall diameter -- the 65
will be the smallest and the 75 will be the tallest.

You might have noticed a loss of traction when you changed from 225s to
235s, because this would represent the width of the tire. A 225/75 and a
235/70 are within 10mm of being the same diameter.

I am a poor judge of what happens in snow, but it's difficult for me to see
where one would notice a difference in 10mm in diameter. I have to suspect
there are tread patterns and other things that enter into the discussion.

Could be, we went from Hercules 'terra Trac' to BFG AT's and it was a
big disappointment. I believe there was over an inch of actual tread
width difference.

Not if the change was from 225 to 235. These numbers represent the tread
width in mm, and 10mm is the functional equivelent of 3/8".

Now, there is some misunderstanding (at least on my part) of just exactly
where they measure 225 or 235, and the actual tread blocks being square on
one tire and rounded off on the other might play a role in your perception
of an inch difference, but the actual difference is 10mm. Your point being
that you are looking at the tread patch on the ground is not lost on me ...

The 'book' width measurements are not at the tread, they are at the
sidewall.

When I went from a 31x10.5" mud to a 33x9.5" mud, the tread on the
ground went from 10.25" to 7.5". I got a 'radical' increase in
traction.
