When its tyres are under-inflatedThis was the right answer

Check your tyre pressures frequently - normally once a week. If they're lower than those recommended by the manufacturer, there will be more 'rolling resistance'. The engine will have to work harder to overcome this, leading to increased fuel consumption.
