Abstract:
The invention relates to a tire comprising a circumferential tread having an outer tread surface and an inner innerliner surface; at least two spaced-apart beads; sidewall portions extending between the tread and the beads; and a belt-like foam noise damper having first and second terminal ends, wherein the noise damper lines the innerliner surface; wherein the noise damper is secured to the innerliner surface via an adhesive situated between the noise damper and the innerliner, wherein the terminal ends of the noise damper are cut at an angle of less than 90 degrees, overlap each other, and the overlapped second terminal end of the foam is joined to the first terminal end by the adhesive present underneath the second terminal end, and wherein the adhesive has weight in the range of 30 to 800 grams per square meter of foam surface.
