They're not claiming to be the largest automotive tire manufacturer.
But structurally they make real tires, as opposed to some other brands, which might produce solid plastic wheels.
They're not pressurized, but neither are e.g. https://crocodiletires.com
If you're going to claim that toys don't count, that's going to get quite fuzzy. Some RC model tires are larger than those on some "real" vehicles.
Because they don’t make the largest tires?
(Joke)
This is clearly not true. All it takes is to acknowledge that Lego produces tires (which it does), check how many they produce per time period (which they provided) l, and compare with other statistics from other tire producers (which they do).
At best, you can claim that your personal definition of what a tire is doesn't match Lego's.

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.
Oh, those are the same Guinness! I always wondered.
No it is, in actuality, a marketing organization. They make all their money selling records. Their business is contracting with companies to come up with a marketable record, and then "observing" the client breaking that record, and then publishing that record. It's no different than those "award" companies that exist only to make up new awards to give companies.
It's the same as when JD power gave Chevy an award for "Highest Initial Quality", as if there is any customer value to a car that starts the best and immediately degrades.
Guiness has always been a half-commercial silly enterprise. It's literally founded by a beer brand to resolve pub trivia arguments.
