description | 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>D2P1>P2P1>=1.2*D1 and P2>=1.2*D22.5 |
