Abstract
A radial tire () for a heavy-duty vehicle of construction plant type, and to reduce the risk of tire tread separation when running over sharp stones, while at the same time ensuring that the crown reinforcement exhibits good resistance to cracking. The tire () has a protective reinforcement () having three protective layers (), comprising metal reinforcers that respectively have a diameter (D1, D2, D3) and are distributed at an axial spacing (P1, P2, P3). According to the invention, with Alpha1, Alpha2 and Alpha3 being the angles of the reinforcers of the respective layers () with the circumferential direction, the following relationships are satisfied:15°≤|Alpha1|≤40°15°≤|Alpha2|≤40°Alpha1*Alpha2≤035°≤|Alpha3|≤75°As regards the differences between the angles of the reinforcers of the protective layers, the following relationship in terms of absolute values applies:|(Alpha1−Alpha3)|≥10°|(Alpha2−Alpha3)|≥10°.
