May 30, 2012
A method for making a tire having a foam noise damper (18) is disclosed. The method comprises the steps of: obtaining a tire (10) having an innerliner (16), the innerliner (16) having a surface (14) facing an interior cavity of the tire (10); applying a foamable liquid to the surface (14); and foaming the foamable liquid to form a solid foam noise damper (18) secured to the innerliner (16). Also, pneumatic tire (10) comprising a carcass (12) comprising an innerliner (16) on the radially inner side of the carcass (12) is disclosed. The innerliner (16) has a surface (14) exposed to an inner cavity of the tire (10) and a foam noise damper (18) disposed thereon. The foam noise damper (18) comprises a silicone rubber foam having a specific gravity in a range of from 0.01 to 0.4.
