1 - 14 . (canceled)
15 . A tire comprising:
an inner liner facing an internal cavity of the tire;
an adhesive layer positioned on said inner liner; and
a strip of noise-damping foam attached to said inner liner by said adhesive layer, wherein the adhesive layer is based on a silanized polyether.
16 . The tire according to claim 05 , wherein the silanized polyether is an alkoxysilane-functional telechelic polyether.
17 . The tire according to claim 16 , wherein the alkoxysilane is methyldimethoxysilane.
18 . The tire according to claim 15 , wherein the polyether is a polyoxypropylene.
19 . The tire according to claim 15 , wherein the foam of the damping foam strip is an open-cell polyurethane foam.
20 . The tire according to claim 15 , wherein the strip is a circumferentially continuous strip.
21 . A method of attaching a strip of noise-damping foam to the surface of an inner liner of a new tire comprising the steps of:
applying a layer of adhesive based on silanized polyether to a surface of the inner liner, to a radially outer surface of the foam strip or to both the surface of the inner liner and the radially outer surface of the foam strip;
positioning the foam strip against the surface of the inner liner; and
leaving the layer of adhesive to crosslink.
22 . The method according to claim 21 further comprising the steps of:
treating the surface of the inner liner of said tire with a high-pressure water jet in order to clean said surface;
drying the surface of the inner liner; and
attaching the strip of noise-damping foam to the surface of the inner liner of the tire.
23 . The method according to claim 21 , wherein the silanized polyether is an alkoxysilane-functional telechelic polyether.
24 . The method according to claim 21 , wherein the alkoxysilane is a methyldimethoxysilane.
25 . The method according to claim 21 , wherein the polyether is a polyoxypropylene.
26 . The method according to claim 21 , wherein the foam of the strip of noise-damping foam is an open-cell polyurethane foam.
27 . The method according to claim 21 , wherein the strip is a circumferentially continuous strip.
28 . The method according to claim 21 , wherein the adhesive is applied by spraying.
