Simple, I saw it on CarThrottle. You must use the nearest round object as a spare tire. Anything usable or are you screwed? I'm screwed:
Crayola Marker Maker... I can use it for different colours to make peoples head explode? Nah me scwood.
I am so screwed... But I beat Metal Gear with just a box, so I think I can pull it off... (It's a fuse by the way, if you hear an ambulance, you will know why.)
