89 Pioneer on BFGs 2235/75/r15. I've only had the jeep since mid-Dec, but we're still good for a couple of good snows here in Denver. So far the thing is fantastic when the weather gets nasty.
I have to say tho, your driving can make as much or more difference than a tire. Just like crawlin' or bombin thru the desert, driving on snow/ice AND getting to your destination w/out any new dents is a skill which takes practice. I've been driving a 2wd dakota on summer tires (225/65/r16) up here for the last ten years (not the same set), and every time it snows I drive by lots of 4x4s in the median/shoulder (even XJs). I bought a pair of snow chains when I moved here but didn't even take them out of the plastic til the blizzard we got hit by last year.
