Abstract: 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.

Abstract: A mold design having a non-symmetric tread ring parting line is described that forms a tread pattern that extends onto the off-shoulder area of a tire on one side. The mold has a single tread segment that forms the entire tread pattern on the tire. The tread segment of the mold is non-symmetric in that one end, a first end, extends farther downward than the opposite end, a second end. The first end of the tread segment contains a tread pattern design capable of imparting a tread design on the off-shoulder or sidewall of one side of the tire to form a non-symmetric tread pattern.

Abstract: A pneumatic race tire has an elastomeric casing with a tread in the crown portion thereof, a pair of bead areas and a body ply carcass extending continuously between the bead areas and through the sidewalls and crown portion. A continuous thin annular band formed of a high strength, lightweight material such as metal, fiberglass, a composite material or the like is located radially inwardly of the tread and between the tread and body ply carcass to enhance tire performance by reducing the thickness of the tread area.

Abstract: A pneumatic tire having a tread, a pair of sidewalls each terminating in an annular bead area, and a pair of beads located within the bead areas, for mounting the tire on a rim. Each of the beads is formed by at least one strand of metallic wire wound upon itself into a spiral and terminating in inner and outer ends, which ends circumferentially overlap each other. The beads are placed in the tire so that the spiral orientation of the beads are opposite to each other and the inner ends of the beads are in substantial axial alignment to reduce radial force variations on the tire.
