A block has a first wall surface formed from a position where a lateral groove is opened to a first circumferential groove toward an upstream side of an air flow, a second wall surface formed from a position where the lateral groove is opened to a second circumferential groove toward the upstream side of the air flow, and a block corner portion formed at a position where the lateral groove is opened to the second circumferential groove. A virtual surface obtained by extending the second wall surface on the upstream side intersects with the block corner portion on a downstream side or passes through a position in the second circumferential groove which is apart from the block corner portion in a tire width direction. A groove width of the first circumferential groove gradually increases toward the downstream side of the air flow at the first wall surface.

A system is disclosed for regulating the pressure of fluid in at least one tire of a vehicle, the system comprising a reservoir comprising fluid at a first pressure higher than the pressure of the fluid in the tire, a compressor configured to receive fluid from the tire and supply it to the reservoir, and processing circuitry configured to receive data representing at least one condition of the fluid in the tire, determine a desired change to the condition, and if the desired change comprises an increase in the pressure of the fluid in the tire, cause fluid from the reservoir to be supplied to the tire or if the desired change comprises a decrease in the pressure of the fluid in the tire, cause fluid from the tire to be supplied to the reservoir via the compressor.

Systems and methods disclosed herein may be useful for use in a wheel assembly which includes a heat shield. In this regard heat shield for a wheel may comprise a first member; a second member positioned radially of the first member defining an annular cavity between the first member and the second member; an opening in at least one of the first member and the second member configured to provide fluidic communication between the annular cavity and an outside of the annular cavity; and a mounting feature in operable communication with the first member and the second member configured to attach the heat shield to the wheel.

Tire cooling systems operatively disposed along a vehicle body adjacent a vehicle tire include a deflector panel displaceable between retracted and deployed positions. In the retracted position, a first nominal volume of air flows along the vehicle tire during operation. In the deployed position, a second nominal volume of air that is greater than the first nominal volume of air is directed along the vehicle tire. An actuator is selectively operable to displace the deflector panel between the retracted and deployed positions. A sensor registers data having a relation to a physical characteristic or health condition of the vehicle tire. A controller executes instructions to determine using the data whether or not the physical characteristic of the vehicle tire exceeds a predetermined threshold as well as control displacement of the deflector panel. Vehicles including tire cooling systems and method of operation are also included.
