I've gone through winters with the toyo at as well as the bfg and a bit on the falkens. The bfg are the best in the snow I've tried and the falken and toyos were both ok, but felt noticeably less stable. All 3 worked well enougb if I didn't drive thousands of miles in the snow every year.I got caught in an early ice storm on near new Nitto ridge grapplers and I was okay, but never want to do it again. I can more comfortably drive at higher speeds with dedicated snows even the moderately priced ones, but would give the edge to the bfg at if you find yourself in deep fresh snow. I have yet to find a winter tire that can brake on ice as well as studded snows. In areas that stay below freezing studs aren't really needed, but I drive a lot of areas that get warm in the day long enough to melt snow only to freeze up agaim so ice is common.I run studs. I've run the same winter tire in a studdable as studded and non studded and will say I notice no difference most of the time, but on ice the studs stop me a bit faster. As far as the op question the pirellis should do fine for the first year with full tread as long as you drive for the conditions, but after that I'd keep them out of the snow and get something else. Either an all terrain like the bfg or get snow tires. Also to note snow tires have 2 different wear bars. Once you reach the first they are no longer snow rated and once you reach the second they're worn out for any road use.
