I think the Escalade must be the most wide SUV on the road based on the way it fills a parking spot.
nah, that's just that select portion of the escalade buying population that couldn't park square within the lines if their life depended on it.
in all seriousness though, if you are looking for an all-terrrain tread, then i think it's a crapshoot on noise. if more of a highway tread is acceptable, then a tire with a solid outer tread bar will be the quietest.
i don't know your exact winter conditions, but for traction, a large solid lug with decent lug spacing is good for mealy ground conditions, but on ice or hard-packed snow, lots of small lugs or siping lines will give you better traction even though the tire may not look aggressive. siping lines, or sipes, are the thin cuts or grooves in a tire that run perpendicular to the direction of the tire. these cuts allow the lugs to flex and put more tire on the road.
another issue i can think of is the weight a tire can carry. with an lt tire, it's probably not much of a concern, but some suv tires may be found without an lt rating. the weight rating (for a tire that size) should be a three digit number which you can cross reference to an actual weight per tire. i've owned european cars, and some have had a history of being a little heavy for their size, and it's been my experience that the lighter tires did not wear as well with my driving habits. i switched from a tire with an 89 rating to a 93 and got better handling and wear from the tires.
