Correct answer
an increase in fuel consumption.
Pressure below the recommended value increases tyre deformation and rolling resistance, which can raise fuel consumption and generate more heat. It does not reduce rolling resistance or fuel consumption. Check pressure when cold and adjust it for the load according to the manufacturer’s instructions; overinflating tyres is not a fuel-saving solution.
