What kind of muddin' are you planning on doing?
The narrower 235's will help you cut through a thin layer of mud (like on wet but fairly packed dirt roads) and the slightly higher profile will give you a bit more ground clearance..

KM2s are great tires for deep snow but they are not siped so in light snow they are not quite as good. I have driven in both here in Pa.

How did you *narrow* your choice to those two sizes?

i was not thinking of mud. This year we used the 235/85 on a Toyota LandCruiser to run in a few Bajas here in Spain, and this tire was very good for us, and of course very hard feeling, and resistant for the stone trails we find in this races.

If you are concerned with ride, he higher profile tires will give you a softer ride if you run slightly lower tire pressure. Both of these tires have approximately the same profile and are ~32" tall.

Since you have 1.25" wheel spacers and will be doing a 3" lift, I'd go with 305/70/16 (a tall and wider 33) or 315/75/16 (a 35) KM2s.
Here is a link (remove the space between the h and the t):

The Goodyear DuraTrac in a 265/75/16 is a 32" tire.

ok, but in this case, i must change the rims because they are stocks rims and i think they are 7ī5, and the 305/70/16 are for 8-9ī5 rims. I am trying not to change the rings.
Thanks for the link

0.5" isn't enough to be concerned about--especially with a 2 door.
The concern about too narrow wheels would be that the tread pattern would not sit flat on the pavement because the beads of the tires would be held in too far. (No se como decir esto en espanol, pero si entiendes lo que he escrito aqui, hablas ingles muy bien.)
Since a 2 door is fairly light, and since you would be running them at a lower air pressure, you would be fine mounting those tires to a 7.5" wheel.

ok, is this what you want to say?...
i donīt know how to say in english, but i think that the ride is gonna be very soft. In spanish we said "flanear", like if you were riding over a muddy surface, isnīt it?

Exactly. The drawing illustrates the concern.
However, the drawing illustrates what might happen if you were running a tire that specified a minimum 10" wheel, you ran it on a 7" wheel, and your air pressure was high.
If you run a tire for an 8" wheel on a 7.5" wheel, and if you run it at a slightly lower air pressure, you will get an even treadwear.
There are many people here running oversize tires on narrower than spec stock wheels. They just air down a little more and their wear pattern and on road performance does not suffer.
