In many jurisdictions, the use of winter tires is mandatory. Additionally, many insurance companies extend a discount for their use, required or not. Changing your own tires with the right tools is a snap, and not only saves you money but also the hassle of making an appointment and waiting for the work to be finished.
If Archimedes* had owned a car, this tool would have been in his trunk. Just shy of 24" long, this breaker bar provides enough leverage to loosen the most stubborn lug bolt; no more stomping on the end of a chintzy OEM tire wrench to try to apply more force. Made of strong, polished chrome-molybdenum steel, it has a swivelling 1/2" head with a ball detent. Just add a 2" or 3" extension and the appropriate socket for your lug nuts, and you're good to go. It's just the right tool for the job.
* "Give me a lever long enough and a fulcrum on which to place it, and I shall move the world."
