Er, no, rolling resistance is coefficient of rolling resistance * normal force. Friction force is coefficient of friction * normal force. Unless you're doing a burnout/drift/launch, this doesn't matter as far as fuel consumption goes because the tire is not slipping. Rolling resistance is the one that matters.
