Since when did German's become experts on tires? I thought you guy's still used wood for wheels(No that was the Dutch and it was shoes wasn't it?) Anyway the steel used in tires is of a transpositional design. That is to say it is transposed over the "rubber"(It is not rubber anymore) This transposition cause the engergy(Read heat) to be dispered within the compound thereby preventing it from building on the outer surfaces of the metal. Steel is by the way "more" pliable than rubber! The only reason a paper clip breaks is the friction produced by the rubbing of the metal against it's self cause it to become molten. Since the heat produced by the metal in the tires is dispered withing the rubber material(Feel your tires after a long drive.) it can't build enough heat to turn it molten and thereby causing a catastrophic failure of the sublimed material. In order to make locks more secure the same technic is used. They are coated with barylium which conducts heat very well and prevent a drill bit from building enough heat to penetrate the metal.
Always happy to help.......
