Robert the Tire is the main character in the 2010 film Rubber. He is an ordinary rubber tire that comes to life and kills people using psychic powers.
Robert is originally inanimate, having been abandoned in a desert along with many other deserted objects. However, he soon inexplicably springs to life and begins rolling aimlessly across the desert sands, discovering that he possesses destructive psychic energy in the process. After testing this power by obliterating several objects as well as a few small animals, Robert eventually encounters humans and quickly becomes a wanted serial killer after causing many people's heads to explode.
At the end of the film, the police locate Robert and shoot him with a shotgun. However, he is instantly reincarnated as a tricycle and continues on his murderous journey, with many other abandoned tires coming to life and following Robert down a long stretch of road.
