Answer & explanation
Official answer
840,000
tires
How to estimate it
Fermi’s official “Napkin math”
Start with the world's 8 billion people. How many buy a LEGO set in a year? It's the biggest toy brand on earth, so call it 1 in 20. Most sets have no wheels at all, but anything with a vehicle has four or five, so across everything it's about a tire per set.
- People in the world
- 8,000,000,000
- Buy a LEGO set in a year
- ≈ 1 in 20
- 8B ÷ 20 ÷ 365
- ≈ 1,100,000
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- LEGO Group tyre production (Guinness World Records)
- ≈ 306 million/year
- ÷ 365 days
- ≈ 840,000
