I'm stuck and could use some opinions/advice. With how good this winter is already looking (compared to the last 3 "winters") I've decided to do something other than my standard Ridge Grapplers for this winter. While I've grown up in CO and never owned actual "winter tires" and have driven from CO to AK to NWT to YT in the winter successfully on AT & MT tires I am at the point in life where why push it rather than just get the right tool for the right job. I live near Vail, CO so we get a fair amount of snow but not necessarily a ton of ice. Which is why I'm stuck. I have big concerns with the Nokians and Blizzaks being way too moderate of a tire tread for deep powdery snow (think offroad, unplowed roads, backroads, winter campsites in Montana, Alberta etc) while there is no question they will be bomber on the slick plowed ice/snow layer on I70 going through town etc. Duratrac and Cooper ST Maxx are both studdable tires with a still decently aggressive tread and seems like a good compromise. I just got back from Svalbard where the roads are solidly packed ice/snow for 5-6 months a year. Were I to be living there, or in Alaska or north east coast with tons of ice and constant packed roads I would worry less about aggressive tread for deep snow. My choice has basically come down to the Nokian Hakkapelite LT2 in a 285/70R17 or Cooper ST Maxx (Studded) in a 285/75R17 with me leaning towards the cooper. Will I be sacrificing too much in all the worlds by going with the Cooper with the more agressive tread over a 100% dedicated snow tire that will probably gunk up and be stuck in thick powdery snow? Thanks
