1. A tire comprising a surface geometry arrangement on a surface of a sidewall portion, wherein the surface geometry arrangement includes a ridge pair in which two ridges bend so as to intersect each other a multiple number of times at corresponding multiple intersection points, wherein the pair of ridges intersect so as to form small area portions that are symmetrical about a reference line extending through the multiple intersection points, wherein the small area portions are free of any surface features, wherein the surface geometry arrangement comprises a plurality of the ridge pairs, and wherein, for adjacent ridge pairs of the plurality of ridge pairs, the ridges of one of the ridge pairs and the ridges of the other of the ridge pairs do not intersect each other.
 
18. A tire comprising a surface geometry arrangement on a surface of a sidewall portion, wherein the surface geometry arrangement includes a ridge pair in which two ridges bend so as to intersect each other a multiple number of times at corresponding multiple intersection points, wherein the pair of ridges intersect so as to form small area portions, wherein the small area portions are free of any surface features, wherein the surface geometry arrangement comprises a plurality of the ridge pairs, and wherein, for adjacent ridge pairs of the plurality of ridge pairs, the ridges of one of the ridge pairs and the ridges of the other of the ridge pairs do not intersect each other.
 
19. A tire comprising a surface geometry arrangement on a surface of a sidewall portion, wherein the surface geometry arrangement includes a ridge pair in which two ridges bend so as to intersect each other a multiple number of times at corresponding multiple intersection points, wherein a reference line extends through all of the multiple intersection points and is parallel to a tire radial direction at all times, wherein the pair of ridges intersect so as to form small area portions, wherein the small area portions are free of any surface features, wherein the surface geometry arrangement comprises a plurality of the ridge pairs, and wherein, for adjacent ridge pairs of the plurality of ridge pairs, the ridges of one of the ridge pairs and the ridges of the other of the ridge pairs do not intersect each other.
