An object of the present invention is to achieve a reduction in weight while securing strength to counter internal pressure in a tire employing a resin material in a tire frame member. A tire (10) includes: a tire frame member (12) formed from a resin mate...

A pneumatic tire (T) has a conductive portion (13), formed by a conductive rubber, provided in the tread rubber (10) formed by a nonconductive rubber. The conductive portion (13) has an outer skin portion (13a) and a projection portion (13b). The outer ski...

A conduction section of a base rubber section and a conduction section of a cap rubber section are reliably conducted with each other. Tread rubber is provided with a base rubber section formed by helically winding a first electrically non-conductive rubbe...

A tire comprising a tread layer comprised of a tread rubber and an electrically conductive band arranged in a widthwise middle portion thereof, and a method of producing the tire, wherein the tread rubber is made of a low-conductive continuous rubber ribbo...

In a method for forming a green tread rubber (TG) comprised of a cap rubber layer (G1) which outer surface forms a tread surface and a base rubber layer (G2) that adjoins the same inside thereof in the radial direction, a cap rubber having a rubber compone...

A tread rubber G has a short-fiber-mixed rubber portion 10 forming a grounding surface. In a region Y1 between an outer grounding end Eo and a tire equator C located outside of a vehicle when a tire is mounted to the vehicle, the short fibers f are incline...
