I've had studded Hakkapeliittas for years, and they are amazing. Other studded snows have two rows of studs around the out-ish edges of the tires. The Hakka's have big gnarly teeth all over the tire. A few years ago we had a very bad ice storm here. I needed to visit a client who had a 1,000 foot driveway, uphill, completely untreated. I drove straight up without any wheel spin. They are loud, but truly amazing.
