My Ranger tremor came with the General grabber AT/X tires 265/70R17. 10k so far and they've been good in snow and mud. Slick clay and mud can wrap around the tires though. Guess that's what the 4wd selection is for. They do clear out quickly once you're out of the mud and they are excellent going up/down steep rock cliffs and over big rocks. Road noise is not bad with the windows down at about 90-100kph. I'll see about noise after some more kms.
Haven't looked at pricing though for replacement.
They can be a bit wobbly feeling on pavement until they get a little heat in them (couple of kms), then they ride well.
YMMV
