    For tire and roller of equal diameter, the rolling resistance is 1.414 × resistance on a flat road, while for a tire three times the roller diameter, easily possible on a brake tester, the resistance is doubled. A typical value for the 'coefficient of friction' (rolling resistance/load) would be 1% for a flat road.
