Provided is a pneumatic tire comprising a tread, sidewalls, a belt, and dimpled patterns, wherein each dimpled pattern is adapted to modify air flow and temperature. The tread defines the outward surface of the tire and extends in a radial direction, a circumferential direction, and a lateral direction. Each sidewall extends radially inwardly along a curved path from the tread to a bead and defines a lateral surface having maximum lateral extent. The belt extends under the tread. Each dimpled pattern is a surface treatment etched from a sidewall maximum lateral extent over a belt edge and onto the tread. Each dimpled pattern surface treatment modifies air flow at 180 mph over the tire to turbulent flow, and reduces steady state operating temperatures of the sidewalls. 1. A pneumatic tire comprising: defining the outward surface of the tire in a radial direction,', 'extending around the tire in a circumferential direction,', 'extending in a lateral direction mutually perpendicular to both the radial direction and the circumferential direction,', a first lateral side, and', 'a second lateral side opposite the first lateral side in the lateral direction;, 'the tread having'}], 'a tread'} from the first side of the tread,', 'to a first bead,', 'the first sidewall defining a first lateral surface having first maximum lateral extent;, 'a first sidewall extending radially inwardly along a curved path'} from the second side of the tread,', 'to a second bead,', 'the second sidewall defining a second lateral surface having second maximum lateral extent;, 'a second sidewall extending radially inwardly along a curved path'}a belt extending under the tread in the circumferential direction and in the lateral direction from a first belt edge to a second belt edge; around the tire circumferentially, and', 'from the first maximum lateral extent radially outward and laterally inward over the first belt edge and onto the tread; and, 'a first dimpled pattern surface treatment etched'} ...
