2015 Q7 TDi Premium Plus. After close call on the Fwy with the last storm we had i decided that i need winters for my Q7 specially driving to mountains with my 2 year old. We go skiing regularly, being in Las Vegas area, its 200 miles to closest ski area in Utah. Sourced used OEM 20" rims. I never used winter tires, always all seasons. My question is which winter tires are good for use both in dry condition and snow. My plan is, every time we go to snow i change the wheels, so i don't ruin the winter tires, on dry pavement. So far I found Nokian Hakkapeliita R3 or Vredestein Wintrac Pro. All suggestions and input appreciated.
