Abstract

A tire having a tire cavity (30), first and second sidewalls (14) extending respectively from first and second tire beads (16) to a tire tread (18) is disclosed. The tire (12) comprises a compression actuator means (19) mounted to the tire (12) within the tire cavity (30) for delivering air to the tire cavity (30). The compression actuator means (19) comprises a containment body (44) formed from a resilient deformable material composition and containing a quantity of a non-compressible medium (48). The containment body (44) is configured to reciprocally transform between a deformed state and a non-deformed state responsive to a deformation and recovery of the tire (12) when the tire (12) is rotating under load. The containment body (44), in the deformed state, is further configured to displace a quantity of the non-compressible medium (48) for generating a compression force to deliver a volume of air to the tire cavity (30). The containment body (44) is shaped to facilitate pivoting during rotation of the tire (12).
