A regulation match football must have an air pressure of between 8.5 and 15.6 PSI (pounds per square inch). Footballs are pumped up to make them travel efficiently.
It's the same for cars, so drive to your nearest garage and check to see if your tyres need pumping up.
What difference does it make?
Properly pumped up tyres can save you up to between 5% and 10% in fuel consumption and help lower your carbon footprint. Win!
