THE ROLLING RESISTANCE OF TIRES UNDER VARYING CONDITIONS OF SPEED, WEIGHT, TEMPERATURE AND INFLATION PRESSURE, WAS DETERMINED ON A TESTER CONSISTING OF A WHEEL AND TIRE RESTING ON THE FACE OF A LARGE WOODEN DRUM, THE TIRE BEING REVOLVED BY ROTATION OF THE DRUM. THE FORCE NECESSARY TO RESIST THE MOVEMENT OF THE WHEEL IS MEASURED ON A PLATFORM SCALE BY MEANS OF A HORIZONTAL ROAD WITH TURN-BUCKLE ADJUSTMENT, A BELL CRANK AND A VERTICAL STAND WHICH RESTS ON THE PLATFORM OF A SCALE. A REMARKABLE CHECK WAS FOUND BETWEEN THE ROLLING RESISTANCE OF FOUR TIRES ON THE TESTER AND OF THE SAME TIRES MOUNTED ON THE ROAD TEST TRUCK AND RUN ON A LEVEL CONCRETE ROAD.
