Title: PNEUMATIC TIRE
Abstract:
The following are defined: a first imaginary line which passes through the ground contact surface in the meridional section of the tread; a second imaginary line which passes through the bottom portion of a shoulder main groove and is parallel to the first imaginary line; the intersection point between the second imaginary line and the surface of a shoulder land section outwards of the ground contact edge in the width direction of the tire; and a tire equatorial plane. Defining A as the distance in the tire width direction between the intersection point and the tire equatorial plane, B as the groove depth of the shoulder main groove, and C as the distance in the tire width direction between the ground contact edge and the tire equatorial plane, the condition 0.80 ≦ (B+C) / A ≦ 1.15 is satisfied; defining M as the distance in the tire radial direction between the bottom of the shoulder main groove and a belt layer, the condition 0.60 ≦ B/(B+M) ≦ 0.75 is satisfied.
