hate the tire thing... but i can sell it quite easily.
"have you ever changed a spare?... oh really?.. never? well, then this works great! not only is it lighter and take up less space (leaving more room for your other stuff), but you don't have to jack up the car, you don't have to turn any wrenches or anything!... besides, for 5 years or 100,000kms, you'll just be calling the roadside assistance which is included at that price!"
personally though, i would be paying for the option or buying one at the scrappers.
