In a car, driving with tyre pressure below the recommended level for the load can...

Correct answer

Increase tyre deformation and heat build-up.

Increase tyre flexing and heat build-up, with a risk of damage or a blowout. It may also promote tread-shoulder wear and increase rolling resistance and fuel use. Heat alone does not explain that extra fuel use. Check pressure when cold according to the manufacturer and load; do not deflate hot tyres or overinflate to try to save fuel.
