Title:
PNEUMATIC TIRE
Document Type and Number:
WIPO Patent Application WO/2015/145909
Kind Code:
A1
Abstract:
This pneumatic tire improves handling stability performance and biased wear resistance performance in a balanced manner. When a curve containing all the points (A1, A2, A3, A4) at both ends in the direction of tire width of a center primary groove (14a, 14b) is a reference profile line (PL0), the profile line (PL1) of the center land section (X) demarcated/formed by the center primary groove protrudes to the outside in the tire radial direction beyond the reference profile line. The profile lines (PL2, PL3) of sub-center land sections (Y1, Y2) and shoulder land sections (Z1, Z2) demarcated/formed in sequence to the outside in the widthwise direction of the tire with respect to the center primary groove protrude to the outside in the tire radial direction beyond the reference profile line.
