Tire comprising an air passageway in a sidewall groove

摘要

A tire with a first and a second sidewall is disclosed. The first sidewall has one bending region operatively bending when radially within a rolling tire footprint. A groove (42) comprising sidewalls is located within the bending region of the first tire sidewall, the groove (42) deforming segment by segment between a non-deformed state and a deformed, constricted state in response to a bending of the first sidewall bending region radially within the rolling tire footprint. An air passageway (43) is defined by the groove (42) and a first cover strip (202) or by the groove (42) and a tube assembly. The air passageway (43) resiliently deforms between an expanded condition and an at least partially collapsed condition in response to a respective segment by segment deformation of the groove (42) when radially within the rolling tire footprint. The first cover strip (202) is located at an open end of the groove (42) for separating the air passageway (43) from ambient air pressure.
