The record is actually pretty clear: https://www.guinnessworldrecords.com/world-records/100909-largest-tyre-manufacture-per-annum https://www.guinnessworldrecords.com/world-records/100909-la... Think of all the makes of tyre you know. Who would make the most tyres each year? The simple answer is Lego! Since 2006, Lego makes around 306 million rubber tyres each year for its construction kit toys. In 2010, this number was topped at 381 million tyres, easily beating all other tyre manufacturers. Even though Lego products are unlikely to fit an everyday car, they do fit all descriptions of a standard tyre, albeit of the solid rubber variety. Even the rubber compound used for the Lego products would not be out of place on a domestic car. "Largest tire manufacturer" could reasonably be interpreted to mean: * Largest company that manufactures tires * Company that produces the most tires by mass/weight/volume * Company that produces the most tires by number of tires If you read the record, it's clear they mean the latter interpretation. By that interpretation, it seems like LEGO clearly is the winner. The things they make are tires: They are rubber-like and go around wheels. There is no rule anywhere on Earth that says tires must not be on toys.
