The pattern is understood to be repeated uniformly throughout the circumference of the tread and buttress and the solid line segments between the outer edges of the shoulder ribs are for the purpose of defining the peripheral boundary of the tread and buttress and form no part of the claimed design.

The broken line showing of the tire sidewall in the drawings is for illustrative purposes only and forms no part of the claimed design.
