I installed these in size 265/70/17(non-studded)for winter mountain pass driving in a lifted 4Runner. Being in Seattle, we don't get much snow, but we've got our few occasional snow storms where we'll get 8-20 over a couple days. During these storms, the roads are poorly maintained as the city lacks the plowing equipment for these days.
First and only major storm we got this year - I was out trying to get stuck on steep hills in 2WD to see how a rear wheel drive vehicle handles snow/ice with winter tires. Like all 2WD cars, you obviously still have to take it easy from a stop to not get excessive tire spin, but these tires do an excellent job at grabbing for whatever traction is available. The only places I got stuck in 2WD were the steepest of hill grades in the Ballard area. We're talking neighborhood hills that people push their bicycles up and kids would sled/snowboard down when its snowing. Once I kicked the truck into 4WD, there was absolutely no slippage and I climbed right up and could go back down safely without ever engaging ABS. In fact, the ABS almost never turns on when I'm in snow/ice unless I'm trying to lock up on purpose. When 4WD is engaged, I could accelerate from stoplights as if it were dry pavement. All in all, I will say my favorite aspect about these tires is the ability to maintain control at all speeds and to stop a car on a dime on compact snow/ice in a fraction of the distance of what my Destination All Terrains can do.
Deep snow traction - I've taken my 4Runner snow wheeling into 1-2ft of powder in eastern Washington and Idaho. They are superb, but definitely have to be careful to go into bumper deep snow as these tires will dig as far as they can go to get traction which can cause me to high center and get stuck.
I've also used these tires in 205/55/16 on a 2005 Mazda 3 Hatch with the same great results.
After 4000 miles, treadwear looks minimal for driving down mostly wet streets/highways.
