Title:
PNEUMATIC TIRE AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2017/159220
Kind Code:
A1
Abstract:
Provided are: a pneumatic tire capable of preventing vulcanization failure, which is a concern when a partial tie rubber layer is employed, and adequately demonstrating reduction in tire weight and rolling resistance due to employing a partial tie rubber layer; and a method for producing the pneumatic tire. A partial tie rubber layer 10 is selectively disposed in each region that is between a carcass layer 4 and an inner liner layer 9 and that is on both sides in the tire width direction of a tread part 1 excluding the center region of the tread part 1. The edge parts of the partial tie rubber layers 10 on both sides in the tire width direction form inclined surfaces acutely angled with respect to the surface of the partial tie rubber layer 10 on the carcass layer 4 side. The incline angle θ of the inclined surfaces with respect to the partial tie rubber layer 10 on the carcass layer 4 side is 20°-60°.
