Title:
PNEUMATIC TIRE
Document Type and Number:
WIPO Patent Application WO/2013/183685
Kind Code:
A1
Abstract:
This pneumatic tire (1) is provided with circumferential main grooves (21, 22) extending in the circumferential direction of the tire and also with land sections (31, 32) divided and formed by the circumferential main grooves (21, 22)(See FIG. 2). The land sections (31, 32) are provided with auxiliary sipes (52). In a plan view of the tread, the auxiliary sipes (52) each have a bent shape formed by connecting first bent sections (521) and second bent sections (522). The depth (Dg) of the circumferential main grooves (21, 22), the depth (Ds_1) of the auxiliary sipes (52) at the first bent sections (521), and the depth (Ds_2) of the sipes at the second bent sections (522) have relationships of 0.5 ≤ Ds_1/Dg ≤1.0 and 0.2 ≤ Ds_2/Ds_1 ≤ 0.5.
