摘要： The subject invention relates to a method of preparing a tire inner surface to attain better adhesion of balance pads, puncture sealants, and noise reduction foams. In this method a strip of multi-axially stretchable film is adhered to the inner surface of an uncured tire with a pressure-sensitive adhesive. Then a release agent coating is applied to the film strip on the inner surface of the uncured tire which is subsequently cured in a suitable mold at an elevated temperature. The cured tire is then removed from the mold and after allowing the cured tire to cool the annular circumferential film strip is removed from the inner surface of the tire to provide a circumferential release coating-free tire inner surface onto which balance pads, puncture sealants, and noise reduction foams can be adhered.

摘要： A self-balancing pneumatic tire is provided having a built-in balancing gel system. In one embodiment, the tire, before cure, includes a green pneumatic tire assembly having an uncured tread defining an outermost layer; a first barrier layer; a second barrier layer situated adjacent the first barrier layer and intermediate the first barrier layer and the tread; and first and second gel precursors. The gel precursors are non-flowable prior to cure but flowable after cure. The gel precursors are respectively contained within spaced-apart first and second circumferential regions defined by confronting, non-contacting surfaces of the first barrier layer and the second barrier layer, each circumferential region further situated proximate opposing sidewalls of the tire and having a width of about 5 percent to about 25 percent of a final tread width obtained upon curing of the uncured tire assembly. In one example, the first and/or second barrier layers can be discontinuous.
