For a car taking a turn on a horizontal surface, let N₁ and N₂ be the normal reactions of the road on the inner and outer wheels respectively. 
 

Let Let O be the center of curvature of the road and C be the center of mass on the car. F₁ and F₂ are the forces of friction on the inner and outer wheels respectively. The torques due to N₁, F₁ and F₂ about C are clockwise; they must balance the anticlockwise torque due to N₂ about C. As N₁ and N₂ are equidistant from C, N₂ > N₁.
