It turns out tires are an integral part of the Lego success story. Lego had been producing kits for more than a decade before the 1962 debut of set #400. That kit included the first version of the now-familiar Lego tire and quickly became a best-seller, accounting for 820,400 sales all on its own in 1967. Before the Lego wheel arrived on the scene and kicked off its revolution, cars in the Lego realm were pre-molded affairs, and some clever children created 8-bit-looking wheels with the Lego bricks themselves.
With such a long history of building beloved toys, you'd think Lego would tie up with a manufacturer of car tires and put the Lego brand on tires we can put on our daily drivers. Make ours Z-Rated, please.
