Abstract

PURPOSE:To improve durability of a heavy-duty radial tire by forming a carcass layer with an aromatic polyamide fiber cord layer of a specific cord angle and by arranging the turnup portion of the carcass layer in a turned-in shape along a bead ring. CONSTITUTION:A carcass layer 4 is formed with an aromatic polyamide fiber cord layer with the cord angle of 90 deg.. A turnup portion 4' of the carcass layer 4 is turned in along a bead ring 6 so that the tip 4'' of the turnup portion is sandwiched between the carcass side layer 4 and the bead ring 6. The turnup portion 4' is fixed to the bead ring 6 with rubber of the JIS hardness of 80-95 deg.. With this constitution, the turnup portion is prevented from coming off or crack ing to improve durability.
