Tyre noise reducing system

摘要

A tire noise reducing system includes a wheel rim, a pneumatic tire mounted on the wheel rim to form an annular tire hollow, and a resonance damper disposed in the annular tire hollow, wherein the damper is one of an annular elastic loose band disposed around the rim and a flexible slack strip having a certain length and fixed to the wheel rim at two points so that a portion between the fixed points slacks, whereby a loose portion of the loose band and the slack portion of the slack strip are risen by a centrifugal force during running to at least partially block the annular tire hollow.
