PNEUMATIC TIRE

Document Type and Number:

WIPO Patent Application WO/2012/091065

Kind Code:

A1

Abstract:

A pneumatic tire with an acoustic damper disposed in a tire cavity and capable of maintaining high-speed durability and productivity while continuing to suppress cavity resonance noise is provided. This pneumatic tire has an acoustic damper, made using an acoustic damping material and attached to the tire inside surface to reduce cavity resonance noise, and comprises a tread of width (TW) that comes in contact with the ground during rolling. The acoustic damper is made from acoustic damping material and is at least one continuous ribbon of width (W) and thickness (E) fixed at an attachment width (Wc) to the tire inside surface within a range of at least 30% of the inside of the tread in the radial direction. The two ends of the continuous ribbons, the start edges and the end edges, are arranged so as to be mutually offset in the axial direction and the continuous ribbons and the tire inside surface form continuous grooves having a groove width (D) that is 10% min., of the width (W) of the continuous ribbons. The attachment width (Wc) is smaller than the continuous ribbon width (W).
