Was wondering about that too. The tires are subject to direct sunlight, and they are black which will absorb much of that energy. Since the vacuum of space insulates, it would get extremely hot. Perhaps they were filled with nitrogen so they wouldn't oxidize. In that case, the tires just have to resist getting gooey and deforming. Perhaps they are capable of withstanding a couple hundred degrees F and relatively low pressure.
