I was a skeptic about snow tires, and with a Range Rover you have a snow mode that can be activated. However, the street truck tires proved to be dismal in 8 of snow we've had in the Northeast. Yet I remained indifferent to snow tires with the presumption that they were incapable of 60mph+ and were too noisy at highway speeds. Then whilst in Germany I rented a BMW X3 SUV fitted with Dunlop M3 snowtires in mid-summer. Wow, that changed everything. 70 mph cruises was dead silent even though the SUV was a diesel fitted with snow tires. And I easily hit 130 mph on stretches of the Autobahn whereby legally permitted, never losing confidence at all. In mountain/urban areas the SUV gripped like a sports car and I averaged 80 mph on country roads. That's when I thought I should replace street tires with snow tires... and I'm glad I did. Nothing much has changed in dynamics, and you can anticipate blizzards or even dry summer pavement. Don't be foolish like I was and invest in snow tires. They really are a quintessential component of winter safety.
