Swapping your snow tires off for regular tires at the end of every winter, and vice-versa at the start of every winter, is one of those tasks, like going to the dentist, that's an annoying inevitability every year. But that doesn't have to be so!
Celsius's Qtires have retractable studs that come out when the weather conditions call for them. I'm not sure exactly how these things work, but apparently they work great as all-weather tires as well as snow tires. Say goodbye to your twice-yearly trips to JiffyLube, my friends.
