When it comes to snow tires, opinions vary. But as I have several years in the tire industry, I'll give you a few of my opinions.
First: Tall narrow tires are generally better than wider tires EXCEPT in really deep snow. The "pizza cutter" type tires are good as long as you're not dragging your front diff. In deep snow, a wider tire will compact the snow and allow you to ride on top of it. Wider tires lose out in 4-5 inch or less snow falls due to increased steering input (wander is increased).
Second: Siping is very important. Sipes are micro sized biting edges and help a great deal in icy situations. Not all tires have "full tread depth" sipes however. All tires (except mud terrain types) have sipes, but check to see if they are full depth or only a couple of 1/32" deep. This will ensure the tire maintains ice traction as it wears.
Third: It's going to be very difficult to beat a true winter tire for snow traction. Look for a giant snowflake on the sidewall to see whether or not it's snow service rated. That designation is different from just an M&S rating.
Fourth: Snow varies in water content, and certain types of tires will show various strengths or weaknesses depending on how wet the snow is. I know people who swear on mud terrains while others say only tall, narrow, all terrain tires work for them.
My suggestion is to base your decision on people with personal experience in your area. Guys who plow snow might be a good place to start as they make their living in the white stuff. Should you choose the 265/75R16 size, I'd recommed the Michelin LTX M/S. It's got full depth siping, silica rubber for increased traction on ice, availability in a 10 ply (load E), and if you run them only in the winter, it should last several years.
Good luck!
