Title:
PNEUMATIC TIRE
Document Type and Number:
WIPO Patent Application WO/2014/057547
Kind Code:
A1
Abstract:
This pneumatic tire (1) comprises: a carcass layer (13); a belt layer (14) which is positioned on the outer side of the carcass layer (13) in the tire diameter direction; and a rubber tread (15) which is positioned on the outer side of the belt layer (14) in the tire diameter direction. The belt layer (14) is formed by layering a pair of intersecting belts (142, 143) having belt angles with absolute values of 10-45[deg] and mutually opposite-signed belt angles, and a circumference-direction reinforcing layer (145) having a belt angle which is within a range of ±5[deg] with respect to the tire circumference direction. A distance (Gcc) from a tread profile (CL) to a tire inner circumference face in a tire equatorial plane and a distance (Gsh) from a tread end (P) to the tire inner circumference face have a relationship of 1.10≤Gsh/Gcc. A degree of shoulder dropping (Dt) of the tread profile in a tire ground contact end (T) and an outer diameter (SH) of the tread profile in the tire equatorial plane (CL) have a relationship of 0≤Dt/SH≤0.015.
