I was never as impressed as some were with the Wildpeak AT3 in the snow. Have liked the Goodyear duratrac, at least on gas trucks. This time I've gone with the Kenda Klever R/T, because it is very similar to the duratrac, has a soft tread compound, and seems to get good reviews for snow use. Way better size availability for these trucks. Will see how they do.
I've always been a fan of aftermarket suspension systems for winter use. They can keep rough and nasty roads with potholes, washboard, or frost heaves from unsettling the rear end of your truck on a slick surface, which often kicks off a slide. The best tires in the world won't help if you can't keep them in contact with the road surface.
We rarely have hardpack out here, its always either loose/unplowed snow, or heavy slush. Rarely ice. They salt the crap out of the roads out here, and everything turns to mush. Totally different philosophy than I've seen out west regarding taking care of the roads. People start complaining if they can't drive their front wheel drive hybrid on summer tires down any road they want 30 mins after it stops snowing. Honestly wish they wouldn't, maybe our trucks would last longer before rusting out.
