Saw a Nissan Altima in a parking lot the other day. It had winter tires, mounted on black steel rims, the smart way to do it (save those alloys for the nice weather).
But each wheel also had one lockable lug nut on it. Maybe the owner had heard about the rising incidence of winter tire theft, due at least in part to Quebec's new law mandating winter tires.
Another manifestation thereof - my daughter Laura has friends in Maine. They tell her that winter tires are in short supply there too - that cross-border shopping thing again.
