From the frictional analysis it is also been proved thatthe contribution of the friction is limited in preventing the sliding phenomenon when a fully fit and with proper inflation pressure rolls on the surface.

From the above things it can also be said that the process of wearing of tires is quick innaturewhenmovingonrigidpavementwithhightexturewavelengththantheother wavelength texture when run for a longer distance. The length of the journey on such surfaces also becomes an important factor in the design.
