Thats an ice tire, not a snow tire. In deep snow, studs do not help at all. When things get soft and smooshy, you want the largest possible tire you can put into your frame. Adding studs to that tire will help you when you hit a patch of polished ice.
Honestly, I rode last winter off road on 26x2.1(closer to 2.0) Nokian 296s (296 carbide tipped studs) and this winter I ride on 29x2.3 (more like 2.25) Exiwolfs. The wider (and longer) Exiwolfs rode much better overall in a snow/ice environment. I only have problems in one spot where the ice was naturally polished. Everywhere the ice has a rough surface that rides just fine.
