摘要： A radial pneumatic tire for a heavy-duty civil engineering vehicle aims to reduce the risk of tread separation of the pneumatic tire, during driving on sharp rocks, while ensuring good resistance to cracking of the crown reinforcement. The pneumatic tire has a protective reinforcement with two protective layers, the radially innermost protective layer having elastic metal reinforcements with a diameter D1 which are axially distributed according to an axial pitch P1, and the radially outermost protective layer has elastic metal reinforcements with a diameter D2 which are axially distributed according to an axial pitch P2. In the tire the following relations are satisfied:
D1>D2
P1>P2
P1>=1.2*D1 and P2>=1.2*D2

摘要： In a pneumatic tire, a first imaginary line passes through a ground contact surface in a meridian cross section of a tread portion and a second imaginary line passes through a bottom portion of a shoulder main groove and is parallel to the first imaginary line. Given A as a distance in the tire lateral direction between an intersection point of the first and second imaginary lines and a tire equatorial plane, B as a groove depth of the shoulder main groove, and C as a distance in the tire lateral direction between the ground contact edge and the tire equatorial plane, the condition 0.80≤(B+C)/A≤1.15 is satisfied and, given M as a distance in a tire radial direction between the bottom portion of the shoulder main groove and a belt layer, the condition 0.60≤B/(B+M)≤0.75 is satisfied.

摘要： A pneumatic tire includes a carcass reinforced by a carcass ply extending from a first bead to a second bead and a belt structure including a first portion and a second portion. The belt structure is disposed radially outward of the carcass ply in a crown portion of the pneumatic tire. The first portion includes a belt with a belt width extending axially from a first shoulder portion of the crown portion to a second shoulder portion of the crown portion. The second portion includes a plurality of bands with band widths less than the belt width. One of the bands has a first group of cords oriented in a first direction relative to a centerline of the pneumatic tire and a second group of cords oriented in a second direction relative to the centerline of the pneumatic tire.
