METHOD OF MAINTAINING A PNEUMATIC TYRE IN ITS OPTIMUM OPERATING CONDITION

摘要

A method of maintaining a pneumatic tyre in its optimum operating condition is disclosed. The method comprises the steps of storing the diameter (r) of an accurately inflated tyre, measuring a distance travelled by the tyre and counting the number of revolutions made by the tyre in travelling that distance. The actual diameter (rx, ry) of the tyre is calculated from the distance travelled and the number of revolutions. The diameter (rx, ry) so calculated is compared with the stored diameter (r) of an accurately inflated tyre to determine any difference between the two diameters. The tyre is then deflated or inflated to conform its diameter to that of an accurately inflated tyre.
