well, for you guys out west, perhaps spares work for you...they don't down here...people get killed on the highways changing them, and that's assuming there is any air in it, or they can actually get the spare off the vehicle...today's lifestyle affords us luxuries...one of those luxuries is being able to call roadside assistance and let them tow the car...even if the car had a spare, let the roadside assistance people do it...sorry, i'm not losing my life over a spare tire.
