After an unfortunate run in with a corn stalk while goose hunting two days ago I finally went with the 31x10.50s from Hercules. They are the Terra Trac ATs. Man those things look good. The road noise is minimal and from what I can tell I really haven't lost that much mpgs. The power loss isn't evident either. I got them mounted and balanced for $340 plus they found me an almost new 31x10.50 to use as my spare seeing as I have the limited slip differential in the back. We had some snow today and I can't wait to see how they perform in the white stuff. They sure do fill up the wheel wells of my 92 much more than those 235/75s did. Anyway, more to come after some in the field testing.
