Yes you can
You can but you should not. The 235/85-16 tire will be way too tall and will have a diameter that is 2.22" larger. This will cause your speedometer to be 4.2 mph too slow at 60 mph. This is not a good swap.

Doubtful, the 225/65 tires are narrower and shorter.
That should be OK, but check carefully for any rubbing.
Can you? Yes. Should you? No. The 235 will be 3.67% smaller. This will adversely effect your ride, handling, speedometer, and braking.
Maybe, if there is clearance for the wider tire.
I guess you can - 235 85 R 16 is a bit narrower and taller. but not vitally. so it would fit
The way you have phrased your question is confusing. If you are saying that the 235/70-16 is the OEM size the answer is NO, this is not an acceptable swap. Going either way this is a bad swap. If your OEM size is 235/70-16 and you want to go to a 75 series tire then you need to install a 215/75-16. If your OEM size is 245/75-16 and you want to go to a 70 series tire then go with a 265/70-16.
That size will work but your speedometer will be off .8 mph too fast.
That should be OK, but check carefully for any rubbing.
No, the 255/70-16 is too large and the diameter will be 1.10" too tall and your speedometer will be 2.2 mph too slow. You are going over 3% difference in size which is never advisable. You can use a 245/70 or a 245/60 but not a 255/70. Make sure all 4 tires are the same size on a 4wd vehicle.
