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.
