What's a northeastern driver to do when wintry roads spell danger for everyday tires, while normal conditions hamper breaking ability for the studded variety? Well, Q's Celsius tires have traction studs that protrude and retract on your command -- practical and 007 slick, like something Q would install for use in rescuing Halle Berry from a gigantic ice palace. How it works: when you're ready to enter extreme weather mode, the tires use their own air supply to fill a secondary chamber that pushes the studs through the surface, past the tread. Then when conditions clear up, the studs retract back below the tread and the surplus air is released. We're not sure how much this upgrade will cost to add little cool to your lemon, but some extra cash might be worth the added safety, not to mention ditching the hassle of seasonal tire switching.
