A tire has at least one band of cooling fins located on a sidewall portion of the tire. The band of cooling fins has at least one protruding cooling fin and at least one recess located adjacent to the cooling fin. At least a portion of the recess is recessed axially inwards relative to the cooling fin. The cooling fin has a height equal to or greater than an airflow boundary layer thickness at a predetermined location and angular velocity of the tire.

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.

A tire-state detection device according to the present invention includes: an electronic component including a detection unit that detects a pressure of a tire; and a case that houses the electronic component. The case includes: a case main body that houses the electronic component and that has an open surface formed thereon; and a lid member that covers the open surface.

Embodiments of the invention include a method of forming a pneumatic tire having a heat insulating layer and a pneumatic tire having a heat insulating layer, for reducing the thermal cooling of a tread of a pneumatic tire. A flexible heat insulating layer is applied to the tire at a location radially inward from the tire tread and opposite the tire tread relative the tire thickness. The heat insulating layer is characterized as having thermally insulating properties configured to maintain at least a portion of the tire tread at or above a desired elevated temperature greater than a glass transition temperature for any such portion of the tire tread under normal tire operating conditions. The heat insulating layer is also characterized as having a low thermal conductivity.

A wheel assembly in accordance with various embodiments for use with an aircraft can include an inner surface, a first lug extending into an area defined by the inner surface and a heat shield configured to be coupled to the first lug. The wheel assembly can also include a gasket configured to be positioned between the inner surface and the heat shield and to remain in place relative to the first lug in response to rotation of the wheel assembly relative to the aircraft.
