Patent number: 8726955Abstract: 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.Type: GrantFiled: November 9, 2010Date of Patent: May 20, 2014Assignee: The Goodyear Tire & Rubber CompanyInventors: Ramendra Nath Majumdar, Giorgio Agostini
